Brian Tooley Racing truck camshafts are the go-to upgrade for LS-based 4.8, 5.3, 6.0, and 6.2 engines that need more torque, power, and sound. These cams are carefully designed to keep low-end torque strong while delivering that aggressive BTR idle LS truck owners love. Whether your build is a street-driven daily, weekend toy, or towing setup, BTR’s truck cam lineup—like the popular Stage 2 and Stage 3 options—offers proven performance, drivability, and reliability. Tested on real-world engines and trusted by countless LS builders, BTR truck cams bring serious attitude and performance to any GM truck platform.
