FEULING PARTS Race Series® Short-Travel Hydraulic Lifters (Set of 4) Race Series® Short-Travel Hydraulic Lifters from FEULING PARTS are engineered to deliver faster valve-train response, reduced valve float, and improved RPM stability—while still maintaining a quiet engine. Built with a revolutionary 0.115" total travel design (vs. 0.200" full-travel lifters), these intake/exhaust hydraulic lifters help reduce valve-train harmonics and keep valve lift under control during high-demand camshaft operation. Key Benefits Higher RPM capability by decreasing valve float and harmonics Reduced oil aeration on steep, fast-action high-lift cam lobes Steel body built for large lift cams and higher spring pressures with slower bleed-down Precision ground needle roller bearing with high chromium steel axle for long life and minimal friction High-flow disc-style check valve for quick reaction at higher RPM Spin-Tron dyno developed and track proven Made in the U.S.A. Compatibility & Use Compatible with Feuling® HP+® or Race Series® oil pumps Designed for street and strip engines Feuling® recommends pumping up lifters by hand before installation Recommended for engines over 185 lb (84 kg) valve spring seat pressure Specifications Type: Hydraulic Applications: Intake & Exhaust Material: Steel Style: Short-Travel Units: Set of 4 Size: 0.8420" – 0.8423" Model: Race Series® Riding Style: Street
New revolutionary design with 0.115" of total travel vs. a full travel lifter with 0.200"
Increases RPM by decreasing valve float and valve-train harmonics while maintaining a quiet engine
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
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
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
Compatible with either Feuling® HP+® or Race Series® oil pumps and are designed for use with both street and strip engines
Maintain proper oil flow to the top end, increase engine RPM, valve-train stability, decreasing valve float promoting maximum valve lift
Precision ground needle roller bearing with high chromium steel axle for long life and minimal friction
High-flow disc-style quick-reacting check valve for better reaction at higher RPM
Spin-Tron dyno developed and track proven
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.
Feuling® recommends Race Series® lifters for engines running higher than 185 lb (84 kg) valve spring seat pressure.
Feuling® recommends the use of a high volume oil pump which will result in quieter, better performing lifters.
