COMP Cams Hydraulic Lifter Set Race XD Chevy SB For .842in

COMP Cams is well-known for pushing the boundaries in valve train technology, and their Race XD Solid Roller Lifters are a prime example of that dedication. If you're building a high-performance Chevrolet Small Block engine with a .842-inch lifter bore, these lifters are designed to handle extreme operating conditions and deliver consistent performance. They are engineered to be the strongest and most versatile solid roller lifters available, offering a robust solution for demanding builds.

What sets these lifters apart is their lightweight, modular design, featuring five interchangeable pushrod seats that allow for significant configurability, even clearing extreme intake angles. They are available in medium or large offsets, with left or right placement options to suit your specific engine setup. The REM-finished bodies create an exceptionally smooth surface, which helps reduce wear on both the lifter body and the lifter bore. For even greater friction reduction and ultimate durability, an optional DLC-coated lifter body is available. COMP Cams also incorporates a proprietary bronze alloy roller bushing for excellent strength and uses a captured link bar to securely join individual lifters together.

A critical aspect of these lifters is their advanced oiling system, specifically developed to combat the common failure point of axle and wheel oil starvation. This system ensures consistent lubrication for the roller wheel and axle, which is crucial for longevity under high stress. These Race XD lifter sets are available in .842-inch and .904-inch diameter bodies for both Chevrolet Small Block and Big Block engines, with various offset seat options to fine-tune your valvetrain geometry. All pushrod seats are designed to accommodate both 5/16-inch and 3/8-inch ball pushrods, making them adaptable to a wide range of setups.
