Feuling Race Series Tappet Set - Standard - 4 stk - 4050

Comes with standard .200" of travel. Standard size is 0.8420" to 0.8423" OD. FEULING RACE SERIES full travel hydraulic lifters are 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. • 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. *FEULING RECOMMENDS PUMPING UP EACH LIFTER BY HAND PRIOR TO 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
