Comp Cams Pro Magnums "R" Reduced Travel Lifters

Comp Cams Pro Magnum Lifters are specifically designed to perfrom at higher engine speeds. When engines are equipped with a hydraulic camshaft, high rpm is limited by the improper position of the internal piston as the lifter inevitably "pumps up". This improper location results in open 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.

Note: These lifters must be installed on egnines with adjustable rocker arms.

Application: LS Series engines originally equpiied with a hydraulic roller cam.
