Valve train innovator adds Small Block Ford to new lifter Applications, taking both the performance and durability of hydraulic Roller lifters to a whole new level. 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 developed the Short Travel Race Hydraulic Roller Lifters using a design that maximizes the performance of hydraulic Roller lifters at higher engine speeds, and now we've added Small Block Fords to the available Applications.
