Feuling FE-4019 0.0015" Oversized Race Lifters for Harley-Davidson Twin Cam 99-17 Models/Sportster/Buell 00-21/Milwaukee-Eight 17-Up

FEULING CASE SAVER Oversized Dia (0.8435 - 0.844)

FEULING® RACE SERIES® lifters are full travel hydraulics, machined from a cold forged steel body and designed to exceed the needs of larger 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.

Due to the unstable nature of this 4 valve engine design with 1 rocker arm activating 2 valve springs Feuling® highly recommends the use of these lifters for Milwaukee Eight engines running a higher lift cam and especially when using higher pressure valve springs. These lifters will help reduce valve-train separation and can result in a quieter, better performing engine. Race Series® lifters are compatible with FEULING® OE+, HP+® or Race Series® and factory oil pumps. Designed for use with both street and strip engines. Spin-Tron dyno developed and track proven, Made in the USA.
