S&S

In 1958 George Smith and his wife Marjorie started a small company called S&S Cycle. Located in Blue Island Illinois, the Smith´s new company began by selling lightweight aluminum pushrods for Harley-Davidson Motorcycles. George Smith´s vision was clear and simple: "I want to make all bikes go faster". This was a goal he pursued for the rest of his life.Even through George an Marge Smith have passed away, the company they founded still shares that vision and S&S Cycle has grown to be the worlds most respected manufacturer of high performance engines and components for American V-Twins.

Products by S&S in our web shop:

S&S HI-4N Ignition

A single/dual fire ignition system with many state-of-the-art features built in a very compact unit. It has four rotary switches for mode selection, advance rate, and rev limit (1500-9900 rpm). Modes are:
single fire, dual fire , OEM curve, race curve, kick start, electric start ,
The aluminum housing protects against vibration, moisture, dirt and improves heat dissipation. Its flange features degree and advance direction markings on the flange. Installation becomes easier with the convenient cable notch in the housing which also helps to prevent cable damage. Built onto the back plate, the sensor/magnet housings protect the sensors from damage during installation. The sensor housings contain advanced flux concentrators (intensify magnetic fields) with high temperature resistant samarium/cobalt magnets for accurate and reliable triggering. For street use the manufacturer recommends coils with a minimum of 2 Ω. Coils with 4Ω or higher may be used but may not produce optimum output.

S&S Compact Ignition Coil 2 Towers

Compact stock-size coils for the special needs of IST and Super Stock ignitions.

Throttle Housings for S&S Grip Assemblies

Throttle Grips for S&S Grip Assemblies

Left Grips for S&S Grip Assemblies

Fuel Line Insulator

Flexible insulator tube which protects the fuel line from scuffing or against heat influence when running it between the cylinders.

S&S Twin Cam Style Oil Filter Bracket

These filter brackets are machined from solid billet aluminum and polished, but since looking good isn´t everything they have some very useful features, too. First, the position of the filter has been shifted slightly to give additional clearance between the filter body and the crankcase for easier filter installation and removal. Second, they are machined to make it easy to install an oil cooler in the pressure side of the system. An oil coolers is especially useful for big inch applications, when towing a trailer or for riding in hot weather conditions. If the cooler is not needed, simply install pipe plugs (included) instead of the hose fittings.

Oil Filter Cartridges for S&S SH and V-Series Engines

Oil filter cartridges which S&S Cycle recommends for their SH-Series (Shovelhead type) and V-Series (Evolution type) engines.

S&S KN-Series Engines

Knucklehead - the name describes a true legend and this engine design is without a doubt one of the important milestones in the history of Harley-Davidson. Introduced in the year 1936 the ohv-engined models in short time became synonyms for sporting, fast and reliable touring machines. Economically this layout proved to be a huge success for the Motor Company, too, because brand followers - and many others - quickly realized the outstanding qualities of this motorcycle. Design and technology of the Knucklehead turned out to be supremely sound and it became the prototype of all Milwaukee Big Twins, which significantly influenced all successive model groups down to the present day. The KN-Series engines by S&S closely resemble the appearance of a stock Knucklehead engine. However, numerous reforms enhance power, engine life, and reliability. The main improvement in design is the 1958-65 style flywheel assembly, which uses a splined sprocket shaft and a Timken sprocket shaft bearing on the drive side. This increased flywheel stability and strenght became necessary to handle the significantly increased power development. The rocker arm cover “tins” are another modern improvement. They are made from die-cast aluminum, and instead of being held in place by the valve guide, they are held down by valve spring pressure. A special gasket on the bottom of the lower “tin” provides a positive seal, and is much easier to service if needed, since the valve guides do not have to be pressed.
The selection includes 93” (1560 cc) engines with crankcases for early style chassis thru 1947, with 1955-64 tin primary and 1936-64 transmissions.
S&S KN-Series engines come completely assembled and ready to run with a electronic S&S Super Stock ignition system and Super E carburetor.

S&S Tapered Performance Mufflers

One of the most popular and cost effective performance upgrades you can make to a Harley-Davidson motorcycle is to replace the stock silencers with a set of low restriction, high performance mufflers. Together with stock exhaust pipes the chromed S&S performance mufflers make a great high performance exhaust system with a low price tag. S&S Slip-On mufflers will increase the performance of any stock engine. S&S slip on mufflers alone will yield almost 8 more horsepower and about 5 foot pounds of torque on a stock 88 cubic inch Twin Cam engine. Even more exciting are the gains that can be had with the addition of an S&S carburetor and cams.

S&S SH74-Series Early Shovelhead Style Engines

The legendary Early Shovelhead generator engine was made by the Motor Company for 4 years only, from 1966-1969, and today it’s a rare bird. This version by S&S with stock 74 cubic inches combines authentic retro style with today’s technology for thousands of trouble-free miles. Fully assembled with the best components S&S has to offer, so factory specs are at least met and in most parts exceeded. The latter include bullet-proof steel flywheels, reinforced connecting rods, billet oil pump, billet rocker boxes, and roller rockerarms. The installed S&S 513G cam provides higher lift and increased valve timing for better performance. Top end oiling is provided through the pushrods which makes external oil lines obsolete.
SH74 Early Shovelhead engines are equipped with an S&S billet timer housing (empty: no ignition components). Ignition rotation is clockwise, like stock. Without intake manifold and carburetor, so you can choose whatever seems appropriate for your needs. Crankcases, cylinder heads and the gear cover have a cast finish, cylinders are black powder-coated and the rocker boxes are polished.

S&S SH80-Series Shovelhead Style Engines

Sometimes stock is enough and this is exactly what the SH80 Shovelhead engine provides. 80 cubic inches of Shovelhead performance which will reliably propel both your daily driver or your end-of-the-world expedition bike. Fully assembled with the best components S&S has to offer, so factory specs are at least met and in most parts exceeded. The latter include bullet-proof steel flywheels, reinforced connecting rods, billet oil pump, billet rocker boxes, roller rockerarms and a billet gear cover. The installed S&S H-grind cam is a dead-on reproduction of the stock H-D cam. SH80 engines come without intake manifold, carburetor and ignition so you can choose whatever seems appropriate for your needs. Crankcases and cylinder heads have a cast finish, cylinders are black powder-coated and the gear cover and rocker boxes are polished. Top end oiling is provided through the pushrods which makes external oil lines obsolete.

S&S Tapered Quick Set up Kits with Air Cleaner and Exhaust

Okay, so maybe your budget isn´t ready for a new big ínch S&S engine yet. But better performance is still within your reach and you can have 10 extra rear wheel horsepower at a price that is about the best deal going. These kits consist of a set of S&S performance mufflers, a high flowing S&S teardrop air cleaner, and a jet kit to re-jet stock carburetors with all components installed in less than an hour. There is no engine work to do, and everything you need is included in the kits. They will fit on either a stock carburetor or a stock 2001-up Delphi style fuel injected throttle body. With the jet kit you can dial in the stock carb for maximum power gains and improved rideability when installed on carbureted bikes. Our testing has shown that fuel map adjustments are normally needed when installed on fuel injected models. It is recommended that the bike be calibrated by your local dealer to insure that the engine is receiving sufficient fuel.

S&S SH93-Series Shovelhead Style Engines

The legend lives! For die-hard Shovelhead enthusiasts we offer these complete, ready-to-install Long Block engines, assembled by S&S builders with the finest parts on the market today. Start with the bullet proof crankcases, flywheels, cylinders, and heads which proved their performance since so many years, and finish with the latest premium valve train components. Crankcases and cylinder heads come with natural aluminum finish, the cast iron cylinders are black powdercoated. Billet gear cover, tappet guides, and rocker boxes look outstanding and offer the kind of performance you expect from an industry leader like S&S.
What you can’t see inside the engine is just as impressive. The S&S Shovelhead style tappet guides are designed around the quiet, dependable Evolution style tappets. The corrected tappet guide bore geometry assures correct valve timing with carefully selected S&S Evolution style camshafts installed in the gearcase. The unique adjustable Quickee pushrods are collapsible for easy removal and installation, but are stronger than stock style pushrods. Inside the billet rocker covers are S&S’s exclusive forged roller rocker arms. Top end oiling is provided through the pushrods which makes external oil lines obsolete. To let them breathe deeply all S&S Shovelhead engines are supplied with a Super E carburetor because tests showed that it provides the best performance on the street.
Last but not least S&S SH engines are equipped with S&S Super Stock ignition systems. All these features result in Shovelhead engines with the kind of quiet power that some folks may just have a hard time believing.

S&S V80-Series Evo Style Engines

For those who don’t want to go “big inch”, the S&S V80 engine provides a down-to-earth performance solution. With the same displacement and physical dimensions as a stock Harley-Davidson Evolution engine, the V80 fits in a stock frame just like the original power plant, but packs a bit more punch, thanks to the S&S 508 camshaft, 585 valve springs and high flow S&S cylinder heads. The V80 is built from the same superior materials as the larger S&S performance engines, so engine life is excellent.
Available with natural aluminum or black powder coat finishes. Rocker housings and nose cone cover are chromed. Fuel and ignition systems are not included, so you can use the carburetor, air cleaner, and aftermarket ignition you may already have. The cylinder heads allow installation of stock length manifolds. V80 Evo Style engines are EFI compatible with aftermarket intake componenets and module - calibration required.

S&S has teamed up with the Gates Corporation, a leading manufacturer of power transmission belts, to offer a series of secondary drive belts for many popular V-twin models. These belts feature Gates’ super strong X3N carbon cord material, which is significantly stronger than the Aramid cables used in many OEM final drive belts.

Replacement Parts for S&S Air Cleaners

S&S Cams for Twin Cam with Chain Drive

The S&S 510C camshaft set is designed to be used with the stock H-D chain drive system and is an economical way to improve the performance of stock and slightly modified street engines. The S&S 510C cams are as quiet as stock but produce significant power increases across the rpm range, especially above 3000 rpm. The 510C cams are compatible with the stock splined chain sprocket used in 2000-up Twin Cam engines, but may be used in 1999 engines if the H-D 2000-up style splined rear cam sprocket is used. S&S’s 1999 FXD test bike produced 62 horsepower in stock con-figuration. Horsepower jumped to over 82 with 88 ft-lb. of torque after the installation of S&S .510" camshafts, adjustable pushrods, an S&S Super E carburetor and air cleaner, 6200 RPM Screamin’ Eagle ignition module, and S&S slip-on mufflers.

S&S Crankcase Breather Reed Valve Evolution

The Evolution style S&S breather reed valve replaces the standard rotary breather valve in 1993→ Evolution Big Twin style engines. Installation is fast and simple. No aligning timing marks, and no rotating parts. There is a +.030“ oversized reed valve for engines with heavily damaged breather bores.
How does it work?
Unlike the rotary breather valve that has been used in Harley-Davidson big twin engines since the 1920‘s, the S&S crankcase breather reed valve is not dependent on the rotation of the crankshaft to make it open and close. Therefore the opening and closing times are not determined by crankshaft position. The functional part of the reed valve consists of three steel reeds that are normally in the closed position. When the pistons travel downward in the cylinders, the air in the crankcase is compressed and pressure in the crankcase below the pistons increases. This pressure causes the reeds to open, allowing the air, oil and oil mist in the crankcase to escape into the cam chest. When the pistons change direction and begin traveling back upward in the cylinders, a vacuum is created in the crankcase. The vacuum causes the reeds to close, preventing air from entering the crankcase. The effect is that a slight vacuum is maintained in the crankcase and oil scavenging is greatly improved. This is most significant at high rpm when the time available to get the air out is the shortest.

S&S 510 G Cams for Twin Cam with Gear Drive

Timing chain or gears? That is here the question. In High Performance engines S&S Cycle prefers gears so their camshaft design for the Twin Cam models features new gears which replace the stock chain drive, sprocket and tensioner system for the cams. While being only slightly noisier than a chain gears incorporate some very important advantages:
increased timing accuracy by eliminating chain lash, almost zero wear compared to a chain, no wear particles in engine oil from tensioner & guides, absolutely safe operation, gears cannot fail and tear,
The latter is a very important factor with the installation of high lift cams and strong valve springs.
S&S Gear Drive camshafts are sold by W&W as complete kits which consist of two camshafts with pressed-on inner drive gears, two outer cam gears, cam bearing plate, four bearings, small parts and gasket.

S&S Cams for Twin Cam Engines with S&S Oil Pump

They are available with 9:1 high compression. Sold as complete kits with front and rear piston, rings, bolts and clips.

O-Rings for S&S Super E/G Crankcase Breather Bolts

S&S Tappet Guides and Quickee Pushrods for Shovelhead

The original Shovelhead hydraulic tappets are not up to the challenge of high performance applications. High rpm, stronger valve springs, and higher lift cams push them beyond their limits. That‘s why most hot rod Shovels are built with (noisy) solid lifters. S&S billet tappet guides for Shovelheads are similar to Evolution style tappet guides and are designed to use Evolution style hydraulic tappets. These tappets have proven themselves in countless high performance Evolution engines where they reduce valve train noise and required maintenance. They work with Quickee Pushrods which S&S has developed with a new type of adjuster that screws into the pushrod until the threads disengage and the adjuster simply slides into the pushrod making installation or removal a snap.

S&S Tappet Guides for Evolution Big Twin

These tappet guides are designed to be stronger, wear better, and last longer than the original counterparts. Use them as stock replacement for OEM  lifter blocks #18623-85A and 18622-85A or to complete your Evo Super Stock crankcases and cylinder heads. Burnished aluminum finish.

S&S Cover for Air Horns

Reproduction of the most sought after part in S&S history: the L-series carb velocity stack cover. In consequence of a high request S&S decided to make a limited run of these covers. Like the original pattern the new one is sand cast. Sold without mounting brackets, which have to be fabricated. They fit all S&S or similar air horns.

S&S Pistons Evo Sportster Conversion 883cc-1200cc

An easy and economic way to increase displacement of 883 and 1100 Evo Sportster models to 1200cc. This kit with 3-1/2” bore forged pistons only requires to bore the stock cylinders from 3 inch to 3-1/2 bore, or purchase new 3-1/2 inch bore cylinders. No combustion chamber modifications or flywheel rebalancing is necessary. Compression ratio will be a very streetable 9.5:1. The piston skirts are coated for reduced friction during break-in.

A redesigned plunger assembly better withstands forces associated with heavy-duty valve springs and cams typically used in high-performance applications. Another feature is a revised metering device which precisely controls oil delivery to top end, insuring rapid lifter pump-up and reducing possibility of oil starvation to bottom end. Each lifter body and plunger assembly is hand-fit and then pressure-tested to insure correct operation.

S&S Semi Solid Adaptor for Evolution Big Twin

S&S Super B Carburetors

The legendary Drag strip and salt lake world record carburetor. A must for all pure-tech aficionados! Conceived for Big Bore and Stroker engines, but yields more power for stock engines, too. The Easyriders Streamliner, the worlds fastest Harley (530 km/h), was equipped with S&S Super B carburetors. Comes without air cleaner and manifold which must be purchased separately.

S&S Super E Carburetor Kits

The S&S Super E and G carburetors are specifically designed for Harley-Davidson Big Twin and Sportster engines. They feature adjustable accelerator pump for instant throttle response at any rpm. The ejector nozzle is located in line between the main discharge tube and the butterfly for undisturbed air flow. With the rider in mind the idle mixture screw has been angled for greater accessibility even with 5 gal. gas tanks. The enrichment device also was refined with a large variable position lever attached to the air cleaner backplate where it is easy to operate even with thick gloves. The throttle spool assembly is designed for later style two cable pull open - pull closed throttle. Cables are not included and must be purchased separately. Following the tradition a teardrop shaped air cleaner has been retained but it was redesigned to reduce the installed lenght of the carb assembly.

S&S Super Stock Shovelhead Cylinder Heads

Primarily designed for stock replacement applications where traditional looks and improved performance are important. These cylinder heads are made from the same high-quality aircraft-cylinder head material like the Evolution heads. The intake port is the same diameter and is positioned in the same location as stock which means stock manifolds bolt right up. A directional vane like the one used in S&S Evo heads to route the air around the valve stem and guide area is located in the floor of the port. Standard intake valve diameter is stock at 1 15/16“. The combustion chamber is identical to stock enabling installation on any engine with hemispherical domed pistons. The exhaust port is also stock configuration and readily accepts stock style exhaust systems. Standard exhaust valve diameter is also stock at 1 3/4“. The pre-installed .590“ lift valve springs are used for greater cam lift versatility, the valve seats are compatible with present day unleaded fuel. Although these heads for Shovel big Twins are designed for stock replacement applications, flow characteristics have been improved up to 9% more flow. S&S Shovelhead cylinder heads easily bolt on and fit like stock. Frame and other clearancing problems are non-existent. Exhaust systems with stock dimensions can be used. Stock rocker cover assemblies are not included and are installed using hardware provided. They are available as stock replacement and as a 2-plug version for 3 5/8” Big Bore cylinders. Each High Output Super Stock Shovelhead cylinder head kit includes front and rear cylinder heads completely assembled with valve seats, valve guides, valves, valve springs, spring collars, valve keepers and valve guide seals ready to run. Also included are gaskets required for installation including cylinder base and head gaskets, rocker cover and exhaust port gaskets, rocker cover and exhaust pipe mounting hardware and installation instructions.

S&S High Volume High Pressure Oil Pump Evolution

The S&S High Volume High Pressure (HVHP) billet oil pump is a high capacity pump that was designed for the S&S Super Sidewinder Plus Engines. The SSW+ engines feature piston cooling jets that spray oil on the underside of the pistons. In order to supply enough oil for the cooling jets in addition to the oil requirements of the rest of the engine, a more efficient pump was needed. Although the HVHP oil pumps are very similar in appearance to the standard S&S billet pumps, there are several important differences.

Special design features:

A new tooth profile with fewer, but larger teeth, provides increased oil volume for both supply and return sides of the pump., Supply gears are 9% wider than stock or standard S&S oil pumps to give the HVHP pump even more oil capacity., Return gears are 28% wider than stock or standard S&S pumps to insure that the additional volume of oil supplied to the engine is scavenged and returned to the oil tank, preventing oil carry over from the crankcase breather., In spite of wider supply and return gears, the HVHP pump is no thicker than stock and uses the stock oil pump drive shaft. , The universal cover has a number of oil feed and return options allowing maximum flexibility for customized installations., Each pump includes supply and return gears, drive shaft, snap rings, miscellaneous hose fittings, gaskets and mounting hardware.,

Drilling Jig for S&S Oil Pumps

S&S Sockets for Main Shaft and Counter Shaft Bearings

Breather Valve for S&S Oil Pump

S&S Crankcase Breather Valve for Twin Cam

Since production start, there have been Twin Cam A engines that have had oil carry over problems, more commonly known as ”oil out the breather“. This is caused by pressure changes in the crankcases as the pistons travel up and down which prevent the oil from the cylinder heads to drain down into the cam chest. Instead oil is trapped in the drain passage. When enough oil accumulates in the rocker boxes, it will start to blow out of the crankcase breather. The problem is generally more common at sustained high speeds, and is also more common in big inch engines. For years, it was something you sometimes just had to live with.
The S&S Crankcase Breather Valve for Twin Cams is an effective and economical solution to these oil carry-over problems in Twin Cams.➻It achieves an improved pressure balance for free oil flow. You can even expect a slight increase in midrange horsepower. Installation is easy and best performed when changing cams or servicing oil pump.
