Feuling M8 Race Series Lifters Standard OD
FEULING RACE SERIES lifters for Milwaukee Eight engines have a relief machined into the lower body to clear the flange on the camshaft front exhaust lobe on grinds using smaller than stock base circles. These 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 valvesprings Feuling highly recommends the use of these lifters for Milwaukee Eight engines running a higher lift cam and higher than stock valve spring seat pressures. This lifter 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 and are designed for use with both street and strip engines. Spin-Tron dyno developed and track proven, Made in the USA.

High flow disc style quick reacting check valve for better reaction at higher RPM.
Available in oversized diameters - Case Savers!
Recommended for both strip and performance street engines
Sold in sets of 4
Made in the U.S.A.
¹ Milwaukee Eight engines must check clearance on front exhaust lifter to camshaft flange fit
*FEULING RECOMMENDS PUMPING UP EACH LIFTER BY HAND DURING 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.
