S&S Cycle Super Stock cylinder head kits feature stock-appearing cylinder heads with improved performance. These heads work well with engines of stock displacement but are ideal for engines with a little larger stroke or bore. They are compatible with stock rocker boxes, intake manifolds, and exhaust. The S&S high-performance valve springs allow for camshafts with larger lifts. Super Stock aluminum cylinder head kits are available in multiple finishes depending on application and they contain all the parts needed for installation except where noted.

An 883 to 1200cc Hooligan cylinder kit for a Harley-Davidson®, like the ones made by S&S Cycle, provides a significant increase in engine displacement, resulting in substantially more power and torque without requiring major engine modifications, making it a popular upgrade for riders seeking better performance on their Sportster 883, with benefits like increased horsepower—by boosting the engine size from 883cc to 1200cc, the Hooligan kit delivers a noticeable power gain, allowing for better acceleration and highway cruising capabilities. Typically these kits are designed as "bolt-on" upgrades, meaning they can be installed without needing extensive machining or engine rebalancing, making the process relatively simple and straightforward. Compared to a complete engine rebuild, a Hooligan kit is a cost-effective way to significantly improve your bike's power. When installing a Hooligan kit, it may be necessary to upgrade the clutch to handle the increased torque produced by the larger engine. Depending on the specific kit and your bike setup, you may need to adjust fuel injection mapping to optimize performance.

Why put your bike engine back together with stock parts—when you can upgrade with one of the S&S Cycle flywheel assemblies? These 3-piece units are forged and heat-treated from 4140 steel, making them harder and stronger than stock. They're precision-machined to be truer (for less vibration), and are assembled with integral mainshafts and lightweight connecting rod forgings. Stock flywheels shift out of true under heavy loads; improve your motorcycle with an S&S Cycle flywheel assembly.
