Feuling 4051 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 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.
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! #4051 / #4052
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 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
