Feuling Race Series Camchest Kits provide a complete solution for Harley-Davidson Milwaukee-Eight engine builders looking to achieve maximum reliability, peak performance, and the coolest operating temperatures available. These comprehensive kits include all necessary components from top to bottom of the camchest, conveniently packaged to ensure every part functions in total harmony. By upgrading the entire oiling system and valvetrain simultaneously, these kits eliminate the guesswork of the ordering process while bulletproofing your engine.

The centerpiece of the Race Series kit is the billet 7075 aluminum oil pump, which is 50% harder and stronger than the factory unit. This design allows for tighter tolerances under high temperatures and features deeper scavenge kidney ports for superior oil return flow. Combined with the High Flow billet camplate, this system significantly increases oil pressure and engine oil flow while reducing wet sumping, blow-by, and oily air cleaners.

• Race Series Oiling System: Includes a billet 7075 oil pump, Race Series lifters, and a High Flow billet 7075 aluminum camplate.
• Performance Gains: Test results show a 2 HP and 2 ft/lbs torque gain at the rear wheel, with a 50% reduction in engine sump oil level.
• Superior Cooling: Engineered to provide 15-25 degree cooler engine temperatures and 15-30 degree cooler oil temperatures.
• Increased Pressure: Delivers 10-30 more PSI of oil pressure and features 27% to 30% more pressure gear volume over stock.
• High-Travel Lifters: Race Series hydraulic lifters feature a full .200” of total travel with a slower bleed-down rate to handle heavy valve spring pressures and increase RPM before valve float.
• Heavy-Duty Components: Kits include fixed-length, heavy-duty pushrods designed to reduce valvetrain harmonics and increase valve lift.
• Premium Hardware: Includes Timken/Koyo cam bearings, ARP cam and crank fasteners, rocker arm studs, nuts, gaskets, O-rings, and assembly lubricants.

Whether your engine is a stock displacement or a large-bore performance build, these kits are designed for quieter and smoother operation throughout the entire RPM range. All kits are proudly made in the U.S.A. and are engineered for both Oil-Cooled and Water-Cooled Milwaukee-Eight models.

Note: Feuling recommends maintaining a proper hot oil level (90%-99% full) for optimal performance. These kits are not legal for sale or use in California on any pollution-controlled motor vehicles.
