Lifters

These High Energy hydraulic roller lifters are for use with the newly designed hydraulic roller cam series from COMP Cams, or as a performance replacement for stock hydraulic roller lifters. You must be certain that the lifter is correct for the type of block used.

These COMP Cams Pro Magnum hydraulic roller lifters are specifically designed to perform at higher engine speeds. When engines are equipped with a hydraulic roller camshaft, high rpm is limited by the improper positioning of the internal piston, as the lifter inevitably "pumps up." This improper location results in broken valves, and, therefore, leads to lost power or sometimes even engine failure. These lifters offer a distinct advantage over standard high-performance hydraulic lifters, especially in race applications where a hydraulic lifter must be used.

With their patented design, plus their capabilities for small base circles and offsets, Super Roller lifters from COMP Cams offer race-proven superior performance and durability. They feature heat-treated chromemoly axles and edge-orifice type oil metering. On top of all of that, they're rebuildable.
