Feuling 4017 Race Series Hydraulic Roller Lifters M8 17-24 & TC
HYDRAULIC ROLLER LIFTERS, Standard OD (0.8420-0.8423), Milwaukee Eight 17-25, 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
-Sold in sets of 4 (See 4017-1 for singles)

*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
