Feuling HP+ Roller Lifters - High-Pressure Cams - Harley & Indian V-Twin
About Feuling
Feuling Parts specializes in the internals that decide whether a big-inch V-twin lives or dies — oil pumps, cam plates, lifters, pushrods and camshafts. Its high-volume oil system components are a standard upgrade on high-mileage and high-output Twin Cam and Milwaukee-Eight engines.
Feuling HP+ Roller Lifters are full-travel hydraulic lifters engineered for performance V-twin engines running aggressive camshaft profiles and high valve spring pressures. Their robust steel-bodied construction and slower bleed-down rate are critical for maintaining consistent oil flow to the top end. This design not only increases RPM capability but also significantly reduces valve float.
Why riders pick this
- Steel body for high valve spring pressures
- Slower bleed-down rate for consistent top-end oiling
- Reduces valve float and improves RPM capability
- Dyno developed and track proven for reliability
- Street and strip engine capable
When pushing the limits of your Harley-Davidson or Indian Motorcycle engine, especially with aggressive cams and stout valve springs, the valvetrain needs components that can keep up. Feuling HP+ Roller Lifters are built to excel in these demanding conditions, providing the stability and control necessary for maximum valve lift and sustained high RPMs. They are a crucial upgrade for any serious performance build.
Uncompromising Valvetrain Stability
- Steel body construction handles valve spring pressures above 185 lbs seat pressure
- Slower bleed-down rate ensures proper top-end oil flow
- Reduces valve float for enhanced valvetrain stability
- Increases RPM capability and promotes maximum lift
- Spin-Tron dyno developed and track proven for reliability
Performance for Street and Strip
These HP+ Roller Lifters are designed for both high-performance street engines and dedicated race applications. Their ability to maintain consistent oiling and reduce valvetrain instability makes them a top choice for riders seeking to extract every bit of power and reliability from their V-twin. For optimal performance, Feuling recommends pairing these lifters with either an HP+ or Race Series oil pump.
