Feuling Tappets

6 products — part of all Tappets

Feuling tappets for Harley-Davidson engines are developed around the same principles driving the brand's Race Series oil systems — measured bleed-down rates, controlled collapse, and the hydraulic characteristics required to work with high-lift camshafts without pump-up or lifter collapse under sustained high-rpm use. The Feuling lifter range covers Twin Cam 1999-2017, Milwaukee-Eight from 2017, XL Sportster 1999-2022, XR1200 2008-2012, and Evolution Big Twin 1984-1999, with high-performance upgrade specifications going beyond OEM replacement. For the Harley-Davidson tuner building a Twin Cam or Milwaukee-Eight for road performance rather than stock reliability, Feuling tappets are matched to the cam profiles and valve spring pressures the application demands. Iron City Motorcycles stocks Feuling lifters for the performance-oriented Harley-Davidson build that needs the valvetrain to keep pace with the rest of the engine.
