Comp Cams Pro Magnum Hydraulic Roller Lifters

High-Performance Roller Lifters to Help Avoid Potential Hassles

These roller lifters are designed to perform at higher engine speeds. When an engine has a hydraulic lifter, high RPM is limited by the improper position of the internal piston as the lifter "pumps up." This problem can result in open valves, thus leading to lost power or sometimes engine failure.
