Application: Chevrolet Big Block Engines with .904" Diameter Lifter Bore.

Race XD lifters for .904" bore Chevrolet Big Blocks are the strongest and most durable bronze bushed solid roller lifter available, featuring a DLC-coated surface that reduces wear with a new oiling design to eliminate oil starvation.

Race XD Solid Roller Lifters are the strongest, most durable and versatile lifters available from the leader in valve train technology, COMP Cams. Designed to be the most versatile solid roller lifters available, COMP Cams Race XD lifters feature a lightweight modular design with five interchangeable pushrod seats. Available in medium or large offsets with left or right placement, the COMP Cams Race XD series lifters are configurable to clear even the most extreme intake angles. REM finished bodies create an extra smooth surface for reduced lifter body and lifter bore wear. An available DLC-coated lifter body coating further minimizes friction for the ultimate in durability. For excellent strength in extreme operating conditions, COMP Cams incorporates a proprietary bronze alloy roller bushing, while a captured link bar joins individual lifters together. In an effort to eliminate the culprit for most roller lifter failures, axle and wheel oil starvation, COMP Cams developed a new oiling system that ensures consistent roller wheel and axle lubrication. COMP Cams Race XD Solid Roller Lifter sets are available in 0.842” and 0.904” diameter bodies for both Chevrolet Small Block and Big Block engines. 0.080” and 0.160” offset seats are available for 0.842” diameter lifters while 0.090” and 0.180” offset seats fit the 0.904” diameter lifters. All pushrod seats are designed to accommodate both 5/16”and 3/8” ball pushrods.
