Upgrade your Harley-Davidson Milwaukee Eight engine with a comprehensive performance solution designed to increase power, reliability, and longevity. These complete cam chest kits provide everything needed to optimize your valvetrain and oiling system, ensuring quieter, smoother operation and superior engine protection. Each kit is engineered to significantly improve engine vitals, offering 15-30 more PSI of oil pressure and increasing oil scavenge volume and flow. These enhancements lead to substantially cooler operating temperatures, reducing engine heat by 15-35 degrees and oil temperatures by 15-30 degrees. By stabilizing oil flow, these components eliminate common issues such as wet sumping, blow-by, and oily air cleaners. The included heavy-duty .165" wall one-piece pushrods are designed to reduce valvetrain harmonics while increasing valve lift for maximum efficiency. Depending on your performance goals, these kits offer distinct power delivery profiles:

• Wide Powerband Profile: Increases torque and horsepower throughout the entire RPM range (1700-5700), performing exceptionally well with slip-on mufflers, full exhaust systems, and high-flow air cleaners.
• Accelerator Profile: Designed for solid bottom-end performance with substantial gains above 2800 RPM (1850-5950), responding best to increased bore and higher compression setups.

Complete Kit Includes:

• Feuling High Volume Oil pump and High Flow billet Camplate
• Reaper series camshaft and hydraulic roller lifters
• Fixed length heavy-duty pushrods
