Competition Cams 875-16 Reduced Travel Hydraulic Roller Lifters for Small Block Chevy 305 and 350c.i. Engines Originally Equipped with Hydraulic Roller Cam, 1987-Present, Including LT1 and LS Series

• .842" diameter; 122g weight; 2.60" seat height
• Designed to perform at higher engine speeds
• Minimize internal piston movement to allow higher engine rpm
• Lifter pre-load should be set at zero to 1/8 of a turn of the wrench on the rocker arm adjusting nut for optimal performance

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. With full travel hydraulic lifters in performance engines, higher rpm are often limited by the incorrect positioning of the lifter’s internal piston, which inevitably “pumps up” during the engine cycle. This improper location results in open valves and therefore leads to lost horsepower and sometimes even engine failure. With the COMP Cams Short Travel Race Hydraulic Roller Lifters, the patent pending design minimizes internal piston movement to cut down on the open valve issues and allow higher engine rpm and thus increase horsepower. The surface of these lifters has been black oxided to significantly reduce surface friction, wear and lubrication temperatures. This creates a high performance, high quality component.
