The COMP Cams Xtreme Energy DLC hydraulic flat tappet lifter set for 4 cylinders is a cost-effective, performance-proven option for GM applications. Each tappet uses a Diamond-Like Coating (DLC) face that creates a hard, lubricious surface to reduce friction at the cam lobe/lifter interface, helping to extend lifter and camshaft life while supporting standard flat tappet valvetrain setups.
