The COMP Cams® Drift Cam is designed for 4.8L/5.3L/5.7L LS swapped drift, road race and autocross cars. Along with major gains in power across the whole RPM range, excellent throttle response is achieved and valve train stability is maintained up to 7500 RPM by using the new LST (Low Shock Technology) lobe design. This stability keeps valve train parts from breaking and helps to maximize the longevity of your LS engine. This .575" lift version is designed to take full advantage of all that our 26906-16 Valve Springs have to offer.
