Feuling, Race series tappet set. STD travel. STD OD

Comes with a standard travel of .200".
Feuling's Race series lifters for M8 engines have a relief machined into the lower body to clear the front exhaust lobe flange of the camshaft on grinds with smaller than stock base circles. These FEULING RACE SERIES lifters are full-travel hydraulic, machined from a cold forged steel body and designed to exceed the demands of higher lift camshafts and higher valve spring pressures, with a slower bleed rate. RACE series lifters maintain proper oil flow to the top end, increase engine RPM, valvetrain stability, decrease valve float and promote maximum valve lift.
Due to the unstable nature of this 4-valve engine design with 1 rocker activating 2 valve springs, Feuling strongly recommends the use of these lifters for M8 engines using a higher-lift camshaft and valve spring seat pressures above stock. This lifter will help reduce valve train separation and can result in a quieter, better-performing engine. Race Series lifters are compatible with Feuling OE+, HP+, Race Series oil pumps and factory pumps, and are designed for use in both street and race engines. Developed on the Spin-Tron dynamometer and track tested, made in the USA.
• Precision-machined needle bearings with high-chrome steel shaft for long service life and minimal friction • Extra-long, cold-forged, precision-machined and fitted plunger for controlled bleeding and pumping • High-flow disc-style quick-response check valve for improved response at higher RPMs.
• Available in oversize diameters – save your cylinder head!
• Recommended for both high-performance track and street engines • Sold in sets of 4 • Made in the USA
¹ M8 engines must check the front exhaust tappet clearance with the camshaft flange
*FEULING RECOMMENDS HAND PUMPING EACH LIFTER DURING INSTALLATION TO REMOVE ALL AIR AND PROVIDE A FULLY PUMPED-UP LIFTER. USING LOW VISCOSITY OIL SUCH AS ATF IN A SPRAY BOTTLE WORKS WELL.
