COMP Cams 99819-16 Race XD REM Finished Bushed Solid Roller Lifters for .842" Chevrolet Big Block

Solid roller lifters for Chevrolet big-block engines, the COMP Cams Race XD 99819-16 are built with a modular design featuring bronze bushings and a.842-inch bore diameter with a.75-inch roller wheel. Each lifter in this 16-piece set accommodates both 5/16-inch and 3/8-inch ball pushrods and features interchangeable pushrod seats. The Race XD series incorporates REM finished steel bodies, a captured link bar system that joins individual lifters together, and a pressurized oiling design to ensure consistent roller wheel and axle lubrication. This design prevents oil starvation, identified as the primary cause of roller lifter failure.
