LIFTER,CS OE DROP-IN

Pro Magnum Hydraulic Roller Lifters Chevrolet 4.3L V6. For use in blocks originally equipped with hydraulic Roller Cam ('87 to present) 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.

Product Overview

*Short Travel Hydraulic Roller Lifters*
When dealing with full travel lifters, certain engines respond better to a light pre-load because it recovers more quickly from any bad harmonics in the valve train. Others work better with a heavy pre-load because oil volume is reduced under the plunger, which increases stiffness. COMP Cams Short Travel Hydraulic Roller Lifters allow you to have the advantages of both light pre-load and reduced oil volume, producing the most stable and highest revving hydraulic lifter available.

Reference Information

Lifters, Hydraulic Roller, Chevy, Set of 12

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.
