COMP Cams 99904-16 Race XD REM Finished Bushed Solid Roller Lifters .904" Chevy Small Block

The COMP Cams 99904-16 Race XD REM Finished Bushed Solid Roller Lifters are the strongest and most durable bronze-bushed solid roller lifters available for .904" bore Chevrolet Small Block engines. Engineered by the industry leader in valvetrain technology, these lifters deliver unmatched versatility, durability, and precision for high-performance and race applications.

Key Features:

• Modular Lightweight Design: Features five interchangeable pushrod seats, reducing overall valvetrain weight while increasing structural integrity.
• Configurable Offset Seats: Available in medium (0.090") and large (0.180") offsets with left or right placement, allowing clearance for even the most extreme aftermarket intake valve angles.
• REM-Finished Body: Proprietary REM surface finishing creates an ultra-smooth lifter body surface that significantly reduces wear on both the lifter and lifter bore.
• Proprietary Bronze Alloy Roller Bushing: A high-strength bronze alloy bushing provides exceptional durability and load capacity under extreme operating conditions.
• Improved Oiling System: A completely redesigned oiling circuit ensures consistent lubrication to the roller wheel and axle, directly addressing the most common cause of roller lifter failure — axle and wheel oil starvation.
• Captured Link Bar Design: A precision-machined link bar connects paired lifters together, maintaining proper alignment and preventing rotation.
• Universal Pushrod Seat Compatibility: All pushrod seats are designed to accept both 5/16" and 3/8" ball-end pushrods.
• 0.904" Body Diameter: Sized specifically for Chevrolet Small Block engines requiring the larger .904" lifter bore.

The COMP Cams Race XD series represents the pinnacle of solid roller lifter engineering, offering a fully configurable system to meet the demands of professional race builds and extreme street/strip applications.
