The Brian Tooley Racing (BTR) Gen III & IV LS Truck Norris Camshaft is engineered to deliver exceptional power and torque across the entire RPM range — a true evolution of BTR’s legendary V2 truck cam series. Developed through extensive in-house cam lobe design and hundreds of hours of dyno testing, the Truck Norris cam refines performance with increased efficiency, broader torque delivery, and stronger top-end power.
With specifications of 212/22X duration, .553/.553 lift, and a 107° lobe separation angle, this camshaft gives LS-based truck engines a commanding, responsive character both on the street and under load. The Truck Norris cam provides that unmistakable “kick in the pants” performance boost while maintaining excellent drivability and reliability — making it the perfect upgrade for everyday performance enthusiasts and towing applications alike.
As with all BTR components, the Truck Norris camshaft reflects Brian Tooley Racing’s dedication to innovation, precision, and race-proven results.
