COMP Cams 15853-16 Short Travel Retro-Fit Hydraulic Roller Lifter Set for Chevrolet Small Block

COMP Cams developed the Short Travel Race Hydraulic Roller Lifters using a patent-pending design to maximize the performance of hydraulic roller lifters at higher engine speeds. When performance engines are equipped with hydraulic lifters, high rpm is limited by the incorrect position of the lifter’s 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. The COMP Cams Short Travel Race Hydraulic Roller Lifters limit that internal movement to a minimum, which cuts down on these issues and allows higher engine rpm. The surface of this newly-designed lifter is REM-finished and oxidized to significantly reduce surface friction, wear and lubrication temperatures. This creates not only a high performance component but an attractive one as well. The patent pending Short Travel Race Hydraulic Roller Lifters are available for GM SBC, LS and BBC engine applications.
