Show original supplier description
The Texas Speed & Performance TSP-Turbo4-3B is a camshaft engineered for 4.8L and 5.3L LS-based engines, particularly those utilizing turbocharging. This Stage 4 turbo cam boasts a .660" lift and a 222/230 duration with a 113 LSA, optimized for boosted performance. To ensure proper operation and clearance, aftermarket pistons with valve reliefs are required. For optimal performance and durability, the use of TSP/PAC double .660 valve springs is recommended. This camshaft is stated to provide great drivability with a nice choppy idle. Custom tuning is required for any camshaft installation to achieve desired performance and ensure engine health. This specific camshaft is compatible with 4WD K1500 models; it will not fit 2WD models.
