COMP Cams 99818DX-2 Race XD DLC Solid Roller Lifters .842 SBC Bronze Bushing No Seats

The COMP Cams 99818DX-2 Race XD Solid Roller Lifters are a premium-grade solid roller lifter set engineered for Chevrolet Small Block engines with a .842" diameter lifter bore. These lifters come with a Diamond-Like Carbon (DLC) finish and feature a proprietary bronze alloy roller bushing for maximum strength and durability in extreme high-performance and racing applications. This set is sold without pushrod seats, allowing racers to select and configure the optimal seat offset for their specific valvetrain geometry.

Key Features:

• DLC (Diamond-Like Carbon) Coating — provides the hardest, smoothest lifter body surface finish available, minimizing friction and maximizing longevity
• Proprietary Bronze Alloy Roller Bushing — replaces traditional needle bearing design for superior strength under extreme operating conditions
• Modular Interchangeable Pushrod Seat Design — five available seat options in medium and large offsets (left and right placement) to clear even the most aggressive intake angles; seats sold separately
• Advanced Oiling System — engineered to deliver consistent roller wheel and axle lubrication, eliminating the primary cause of roller lifter failure
• REM-Finished Lifter Body — creates an ultra-smooth surface that reduces lifter body and lifter bore wear
• Captured Link Bar Design — joins individual lifters together for added stability and retention
• Compatible with 5/16" and 3/8" Ball Pushrods — when used with separately purchased pushrod seats
• .842" Diameter Body — fits Chevrolet Small Block applications

The Race XD line represents COMP Cams' most advanced solid roller lifter platform, combining the best engineering features from their Elite Race and Sportsman lifter series. The interchangeable seat system allows builders to use the minimum offset required for port clearance, reducing stress on the lifter and dramatically extending service life. Backed by a limited lifetime warranty against manufacturer defects.
