The TSP 4.8/5.3 Stage 4 Turbo Cam is specifically designed for smaller cubic inch motors such as the 4.8/5.3 when using single or twin-turbos. The stage 4 is our biggest offering for our 4.8/5.3 turbo applications and will offer the maximum amount of power out of your boosted 4.8/5.3 possible. This camshaft will work in stock turbo’d applications or a wild built forged motor! Our TSP/PAC double .660 valve springs are recommended for this cam and turbo applications in general for extra reliability and safety, as well as our chromoly hardened pushrods. Our stage 4 turbo cam still retains good drivability while offering the most amount of power available from your turbo 4.8/5.3 LS! Great chop at idle too!
Note: Valve Springs Required Use TSP.660 Dual Valve Springs.
