COMP Cams Stage 1 Thumpr Cam for Gen IV LS 4.8L/5.3L/6.0L Truck

If you're looking to give your Gen IV LS truck engine a more aggressive idle and a noticeable bump in power, this COMP Cams Stage 1 Thumpr Camshaft is a solid choice. It's specifically designed for 4.8L, 5.3L, and 6.0L truck engines, offering that classic Thumpr sound and improved performance without needing new valve springs. This camshaft is a popular upgrade for truck owners who want a more engaging driving experience and better throttle response.

This particular camshaft, part number 54-701-11, is a Stage 1 grind, meaning it balances a strong, lopey idle with street-friendly drivability and power gains. It's a hydraulic roller camshaft, which is standard for modern LS engines, and it's designed to work with your engine's factory valve springs, simplifying installation. Importantly, this cam requires an AFM (Active Fuel Management) and VVT (Variable Valve Timing) delete, which is common when upgrading to a more aggressive camshaft to ensure proper operation and prevent potential issues.

This camshaft fits a wide range of GM vehicles, including popular models like the Chevrolet Silverado 1500, GMC Sierra 1500, and Chevrolet Tahoe. When installing this camshaft, remember that it requires the removal of the Active Fuel Management (AFM) and Variable Valve Timing (VVT) systems. It's always a good idea to consult the manufacturer's installation instructions for specific details on required components and procedures to ensure a smooth and successful upgrade.
