COMP Cams® introduces a high-quality yet affordable alternative to hard-to-find traditional iron flat-tappet lifters for popular solid and hydraulic flat-tappet applications. The new Xtreme Energy™ Diamond-Like Carbon (DLC) coated flat-tappet lifters feature a DLC surface treatment, producing a flat-tappet lifter with an extremely hard, tough, and slick face that reduces friction at the cam lobe. This coating also extends the life of the lifter and camshaft, significantly reducing the likelihood of a flattened cam lobe. DLC-coated lifters are compatible with all steel and cast-iron camshafts and have been durability tested on a Spintron, simulating entire racing seasons with outstanding results. Available for Chevrolet, Buick, Cadillac, Pontiac, Oldsmobile, Ford, Chrysler, and AMC applications requiring flat tappets and are available as singles or I4/I6/V6/V8 sets.
