Brian Tooley Racing camshafts for Gen 5 LT engines are engineered to make modern performance simple and reliable. Designed for LT1, LT4, LV3, L83, and L86 platforms, each BTR grind is optimized for direct-injected engines and compatible with AFM and VVT delete setups. Whether you’re chasing better throttle response in an Gen V LT1 Camaro or more torque from an L86 truck, BTR’s Gen 5 cams deliver the perfect balance of drivability, sound, and power. Built with the same precision and testing that define BTR’s LS lineup, these cams unlock the true potential of your late-model GM engine.
