Lifter - OEM-Style - Hydraulic Roller - 0.842 in OD - Reduced Travel - Small Block Chevy / LS-Series - Each

COMP Cams Lifter CS OE Drop-In Hydraulic Roller S

Pro Magnum Hydraulic Roller Lifters Chevrolet Small block. For use in blocks originally equipped with hydraulic Roller cam. 1987 to present, and Gen III, LS1, LS2, and LS6. COMP Cams Pro Magnum Hydraulic Roller Lifters are specifically designed to perform 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. NOTE: These lifters require an adjustable valve train and must be pre-loaded to .002" to .004" for proper operation!

Reference Information

Lifter, Hydraulic Roller, Chevy, Each

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.
