Brian Tooley Racing's Stage 2 Truck V3 camshaft is a great choice for stock torque converter vehicles looking to kick the power and sound up a notch. It will have a mild but noticeable camshaft chop sound at idle and produces gains of 50+ horsepower over the stock camshaft in 5.3L applications. Perfect for those who want to add fun to their daily driver without needing to switch to an aftermarket torque converter.
The new BTR V3 Truck Camshafts are the result of their most extensive truck cam development program ever, delivering more average torque and horsepower under the curve—perfect for trucks that need strong midrange performance & enhanced towing capability.
The V3 cams use advanced valvetrain simulation and dynamic modeling tools along with Spintron development to guarantee reliable, stable valvetrain performance across all possible platforms. Next, BTR used engine and chassis dyno testing, using full-length truck exhaust systems and OEM-style intakes. Hundreds of dyno runs were performed to fine-tune cam timing, maximizing torque and efficiency across the RPM range.
These “Truck” cams receive the same engineering rigor and combustion development as BTR's race programs. No old catalog lobes! Plus, you're getting a 100% USA-designed & made product!

Note:
- DOD/AFM equipped engines will require a DOD/AFM Delete Kit
- VVT engines will require a VVT Delete Kit
- If installing in an engine originally equipped with a 1-bolt camshaft, a 3 bolt conversion kit will be required
- Due to their heavier valve weight, BTR SK018 springs are recommended for 6.2L engines and 2007-later rectangle port 6.0L engines. See Rectangle Port Cam Kit Listing Here
