Comp Cams GM/LS Reduced travel Hydraulic Roller Lifters

COMP Cams Reduced travel Performance hydraulic roller lifters have been engineered from a patent-pending design that specifically performs at higher engine speeds. They are designed to limit the lifter's internal piston as it is pumped up. By limiting that movement, the COMP Cams Reduced travel hydraulic roller lifters cut down on the loss of power and limit valvetrain failure at higher rpm.

Designed to perform at higher engine speeds
When equipped with hydraulic lifters, high rpm is limited by improper position of lifter's internal piston as lifter "pumps up"
Improper location results in open valves that lead to lost power and possibly engine failure
Minimize internal piston movement to allow higher engine rpm
