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 180 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.

*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
