fits  17-25 M8

Comes with standard .200″ of travel. Feuling Race Series lifters for M8 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 valve springs Feuling highly recommends the use of these lifters for M8 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. • 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! • Recommended for both strip and performance street engines • Sold in sets of 4 • Made in the U.S.A. ¹ M8 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. See Feuling tool 588060 to check lifter bore diameters

Home > Parts > Engine > Lower End > Tappets > Feuling, Race Series tappet set. STD travel. +.015″ OD

fits  17-25 M8

Comes with shorter .115″ of travel. New revolutionary design with 0.115″ of total travel vs. a full travel lifter with 0.200″. These hydraulic lifters will increase RPM by decreasing valve float and valve-train harmonics while maintaining a quiet engine. The travel reduction reduces the amount of oil that is required to fill the inside of the lifter which reduces oil aeration inside the lifter on steep, fast action high lift camshaft lobes. NOTE: when oil aeration is present inside the lifter, the pushrod seat drops when the lifter rolls onto the front cam lobe ramp after squeezing the aeration down thus creating a noisy poor performing lifter. Feuling short travel lifters should be set with 0.065″ – 0.070″ of pre-load and with the normal engine growth from heat will put the operating lifter pre load at or around half travel. Machined from a steel body and designed to exceed the needs of large 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. Feuling recommends Race Series lifters for engines running higher than 185 Lbs. valve spring seat pressure. FEULING recommends the use of a high volume oil pump which will result in quieter, better performing lifters. Race Series lifters are compatible with either FEULING HP+ or Race Series oil pumps and are designed for use with both street and strip engines. Spin-Tron dyno developed and track proven, Made in the USA. • Better Performance! • Quieter running engine! • Stock replacement to full out Drag race • Adjust FEULING SHORT TRAVEL lifters with 0.065″ – 0.070″ of pre load on the lifter. • 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!, Ideal side clearance is 0.001″ • Recommended for both strip and performance street engines • Sold in sets of 4 • Made in the U.S.A. *FEULING RECOMMENDS PUMPING UP EACH LIFTER BY HAND PRIOR TO INSTALLATION, TO REMOVE ALL AIR AND PROVIDE A FULLY PUMPED UP LIFTER.

Increase the M8 oil pump pressure relief pop off pressure with a Feuling spring. Our spring has the proper spring rate to control the pop off pressure and oil flow in the by pass port. This spring has increased pressure when compared to the stock spring, aiding seat pressure and increasing the overall pop off pressure. Repl. 26210-99. NOTE: Feuling oil pumps are pre set with the proper pop off and valve seal at the factory.
