NSR Drift 233/243 Hydraulic Roller Cam for GM LS GEN III/IV
The NSR (No Springs Required) Drift Cam for GM 4.8-5.7 LS is a drop in camshaft upgrade designed to wake up smaller displacement LS's and provide a wide, usable power increase for the grassroots enthusiast.
The COMP Cams® No Springs Required Drift Cam is the first camshaft specifically designed for 4.8/5.3 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 cam has already proven itself in Pro-Am Drifting and SCCA Autocross competition!
