S&S Cycle 124 in. Power Packages with Gear Drive Cam
S&S Cycle 124 in. power packages with gear drive cam are the ideal combination of performance and savings to transform a Harley-Davidson® motorcycle without breaking the bank. Each kit is tailored with the necessary components for your specific HD® model. These kits offer significant benefits, including a substantial increase in horsepower and torque across the powerband, improved throttle response, better cam timing accuracy due to the gear drive mechanism, and a more reliable valve train compared to a standard chain-driven cam, making it ideal for riders seeking a powerful and responsive engine upgrade, especially on larger displacement bikes like the Milwaukee-Eight models. Installing a 124 in. power package often necessitates additional tuning adjustments, including adjusting fuel delivery and ignition timing to optimize performance. Select the power package with gear drive cam designed specifically for your HD® model and engine to ensure proper fitment.

Vertex Race Piston Kits
Vertex Race piston kits consist of piston, rings, wrist pin, and circlips. These pistons are made from the highest quality 2618 aluminum alloy and are perfectly suited to handle the rigors and high pressures of today's modern four-stroke engines. Plus, to aid in the break-in process and reduce wear, every Vertex piston utilizes a unique Molybdenum Disulphide (MOS2) coating on the piston skirt. What truly sets Vertex pistons apart from the competition are the unique piston profiles and compression ratios that are offered in A, B, C, and D sizes. This variation in sizing allows the piston to be perfectly sized to the cylinder for maximizing power and performance, while reducing blow-by and oil consumption. Order the piston kit designed to fit your application needs.
