Feuling, Race Series Lifters

FEULING Oversized Dia. (0.843" - 0.8435") 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 â 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. / Fitment: 99-17 (NU) Twin Cam; 17-25 M8 (Excl. 23-25 CVO with 121" engine); 00-22 (NU) XL Sportster; 08-12 (NU) XR1200; 00-10 (NU) Buell XB
