RACE SERIES LIFTER – M8/TC/XL

Description

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. -Precision ground needle roller bearing with high chromium steel axle for long life and minimal friction-Cold forged extra long piston, precision ground and fitted for controlled leak down and pump up-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-4017-1 Sold each (See 4017 for 4 pack)-Made in the U.S.A.*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
