COMP Cams 99818DX-16 Race XD Solid Roller Lifter Set .842" SBC Bronze Bushing DLC Finish

The COMP Cams 99818DX-16 Race XD solid roller lifter set delivers race-proven performance for .842" bore Chevrolet Small Block engines. This 16-piece set features a Diamond-Like Carbon (DLC) coated lifter body combined with a proprietary bronze alloy roller bushing for maximum durability and reduced friction in high-demand racing applications. Pushrod seats are not included, allowing builders to select the correct offset seat for their specific application.

Key Features:

• DLC-Coated Body: Diamond-Like Carbon finish minimizes friction and wear beyond what REM finishing alone provides, delivering the ultimate in lifter durability
• Proprietary Bronze Alloy Bushing: Engineered for excellent strength under extreme operating conditions, replacing conventional needle bearings for superior load capacity
• Revised Oiling System: Purpose-built oiling design ensures consistent roller wheel and axle lubrication, directly addressing the primary cause of roller lifter failure — oil starvation
• Lightweight Modular Design: Five interchangeable pushrod seats (sold separately) available in medium and large offsets with left or right placement to clear even the most extreme intake angles
• Captured Link Bar: Joins individual lifters together for a secure, reliable assembly
• .842" Body Diameter: Designed specifically for Chevrolet Small Block applications
• No Pushrod Seats Included: Select offset seats separately (0.080" or 0.160" offset available); all seats accommodate both 5/16" and 3/8" ball pushrods

The Race XD series represents COMP Cams' top-tier solid roller lifter technology, engineered for racers who demand maximum valvetrain performance and reliability. For the REM-finished version without DLC coating, see part number 99818-16.
