Everything looks great, just a little disappointed that the cam plate is not red. I was thinking of getting the RS see through cover but won't now.

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 Race Series hydraulic lifters are purpose-built for the demands of high-performance V-twin engines. Engineered to support aggressive camshaft profiles and high valve spring pressures, they ensure stable and efficient valve operation. These lifters maintain consistent oil flow to the top end, crucial for both street and track applications.
Why riders pick this
- Steel body construction for high valve spring pressures
- Slower bleed-down rate for consistent top-end oil flow
- Reduces valve float and promotes maximum valve lift
- Dyno developed and track proven performance
- Compatible with Feuling HP+ and Race Series oil pumps
When you're pushing your Harley V-twin with a high-lift cam and stronger valve springs, stock lifters can become a weak link. Feuling Race Series lifters are designed to handle these elevated demands, ensuring your valvetrain remains stable and responsive. Their robust construction and optimized bleed-down rate help reduce valve float, allowing your engine to reach its full potential.
