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 lifters are built for the most demanding V-twin engine applications. These full-travel hydraulic lifters are machined from robust steel and engineered to thrive with large-lift camshafts and extreme valve spring pressures. Their slower bleed-down rate is key to maintaining valvetrain stability and consistent oil flow to the top end.
