COMP Cams Stage 2 Thumpr Camshaft for Gen LV LS 4.8/5.3/6.0L Truck

This is the COMP Cams Stage 2 Thumpr Camshaft, part number 54-703-11, designed for GM Gen IV LS engines found in a wide range of trucks and performance vehicles. If you're looking to give your 4.8L, 5.3L, or 6.0L truck engine that classic, aggressive idle lope and unlock more power, this camshaft is a solid choice. It's specifically tuned with the Thumpr lobe design to create that distinctive sound while improving performance.

This camshaft requires a delete for Active Fuel Management (AFM) and Variable Valve Timing (VVT) systems, meaning it's intended for modified engines where those systems are being bypassed. To handle the increased lift and ensure maximum power gains, you'll need to use high-lift valve springs, which are not included with the camshaft itself. The Stage 2 grind offers a noticeable bump in performance over stock, making it a popular option for truck owners aiming for a more potent and audibly aggressive powertrain.

When installing this camshaft, remember that it's a significant upgrade that will change the engine's character. It's recommended to consult with a professional or refer to the manufacturer's detailed installation instructions to ensure proper setup, especially regarding the valve springs and the AFM/VVT delete. This camshaft is not CARB approved and cannot be shipped to California.
