Product Details
Harley Davidson Fat Boy 2007, Race Series Hydraulic Lifters by Feuling®. With axle oiling, Standard OD. Race Series full travel hydraulic lifters are machined from a steel body and designed to exceed the needs of large lift camshafts and higher valve spring pressures with a slower bleed down rate. RACE SERIES® lifters maintain proper oil flow to the top end, increase engine RPM, valve-train stability, decreasing valve float promoting maximum valve lift. Feuling® recommends Race Series® lifters for engines running higher than 185 Lbs. valve spring seat pressure. FEULING recommends the use of a high volume oil pump which will result in quieter, better performing lifters. Race Series® lifters are compatible with either Race Series® oil pumps and are designed for use with both street and strip engines. Spin-Tron dyno developed and track proven.

Feuling® Recommends Pumping Up Each Lifter by Hand Prior to Installation, to Remove All Air and Provide a Fully Pumped Up Lifter. Use of a Thin Weight Oil Like Atf in a Squirt Can Works Well.
