Fox Racing Shox Street Performance RC1 Shocks

Fox Racing Shox Street Performance RC1 V-Twin rear shocks are designed to maintain damping control throughout your ride. The internal floating piston is housed in an external reservoir to separate the shock oil from the nitrogen gas so they can never mix like stock shocks.

FOX's 24-position compression adjustment on the reservoir allows you to fine-tune for the softest ride without bottoming out; while the rebound control with 12 distinct clicks can balance out your spring preload, keeping the rear wheel firmly planted—no matter how much or how little preload you have on your springs. If that wasn't enough, the vehicle-specific damping and linear spring rates give you the best in comfort and control for all-day adventures.

S&S Cycle 883 to 1200cc Hooligan Cylinder Kits

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.
