Feuling Performance Hydraulic Roller Lifter - Harley Sportster
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.
The Feuling performance hydraulic roller lifter is engineered to deliver superior oil flow and reduce wear within your Sportster's valvetrain. This upgrade helps maintain optimal engine health and extends the life of critical components.
Why riders pick this
- Optimized oil flow to valvetrain components
- Reduces top-end wear for extended engine life
- CNC machined and precision ground
- Direct drop-in replacement for OEM lifters
- Dyno developed and track tested
- Recommended with high-volume oil pumps
For Sportster riders looking to enhance engine durability and performance, Feuling's roller lifters are a crucial upgrade. Each lifter is CNC machined and precision ground, ensuring consistent and optimized oil delivery to the top end. This targeted lubrication minimizes friction and heat, significantly reducing wear on valves, springs, rockers, and shaft components, which are often prone to stress in high-performance applications.

Built for the Ride
Feuling roller lifters are dyno developed and track tested, proving their capability to handle the demands of both daily riding and spirited performance. While they are a direct replacement for stock units, pairing them with a Feuling high-volume oil pump or an equivalent is recommended to maximize their benefits. Made in the U.S.A., these lifters bring American-made quality and engineering to your Sportster, ensuring reliable and consistent performance.
