HYDRAULIC ROLLER LIFTERS, Standard OD (0.8420"-0.8423"), Milwaukee Eight '17-'26, T/C '99 - '17, XL And Buell '00 - '22

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 especially when using higher pressure valvesprings. 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.

-High flow disc style quick reacting check valve for better reaction at higher RPM.

-Available in oversized diameters – Case Savers! #4018 or #4019

-Recommended for engines with higher valvespring pressures and/or aggressive camshafts. Can also be used in stock applications as a premium replacement.

-Relief machined into the lower body to clear the flange on the camshaft front exhaust lobe on grinds using smaller than stock base circles

*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. SEE TOOL #9005

*PROPER LIFTER BORE TO LIFTER CLEARANCE IS CRUCIAL FOR OPERATION. SEE TOOL #9004
