With continuous advancements in valve train technology, engine builders and performance

enthusiasts alike are witnessing more aggressive cam profiles, higher valve spring pressures and

higher engine rpm. Far too often, hydraulic lifters get caught in the middle of these competitive

valve train innovations. That’s why engineers at COMP Cams® have recently 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 then black oxided 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, LS1/Warhawk/LSX and BBC engine

applications.
