BTR Brian Tooley Racing "Truck Norris" Camshaft
 
For 1999–2013 GM Gen 3/4 LS Cathedral Port Truck Engines – 4.8L 5.3L 6.0L
 
The BTR "Truck Norris" camshaft delivers a roundhouse kick of power and torque to your 1999–2013 GM V8 truck or SUV. Developed through hundreds of hours of in-house cam lobe design and dyno testing, it outperforms BTR’s legendary V2 truck cams with stronger gains across the entire RPM range. It offers an aggressive, head-turning idle while still maintaining good street manners with a stock torque converter.
