COMP Cams Race XD Mechanical Roller Lifters

COMP Cams Race XD mechanical roller lifters are strong, durable, and versatile. They feature a lightweight modular design with interchangeable pushrod seats. Available in medium or large offsets with left or right placement, Race XD lifters are configurable to clear the most extreme intake angles. Two finishes are offered: REM finished bodies create an extra-smooth surface for reduced lifter body and bore wear; and the DLC-coated bodies further minimize friction for the ultimate in durability. For excellent strength in extreme operating conditions, COMP Cams also enhances their Race XD lifters with a proprietary bronze alloy roller wheel bushing and an oversized captured link bar to connect the individual lifters. In an effort to eliminate the culprit of most roller lifter failures, these bushed solid roller lifter sets have oiling systems that ensure consistent roller wheel and axle lubrication. Order the lifters recommended for your year/make and engine application.
