GEN 3 & 4 LS Stage 2 Truck Cam

The GEN 3 & 4 LS Stage 2 Truck Cam from Brian Tooley Racing is engineered for LS engine builders seeking increased valve lift and duration without sacrificing daily drivability or reliability. This hydraulic roller camshaft is purpose-built for Gen 3 and Gen 4 LS-platform engines, delivering the aggressive grind geometry necessary for truck applications that demand both power and practicality. Whether you're upgrading a stock LQ4, LQ9, LS3, or LS7-based platform, this Stage 2 profile bridges the gap between mild street performance and serious track capability.

Brian Tooley Racing's cam grinding specialists optimized this profile for peak torque production in the mid-to-high RPM band while maintaining acceptable cylinder pressures and valve train harmonics. The Stage 2 designation indicates a moderately aggressive lift and duration curve that maximizes flow through ported heads without requiring fueling adjustments or turbocharger compensation on naturally aspirated builds. The cam's precision-ground lobes work seamlessly with OEM hydraulic roller lifters and factory push rods, eliminating compatibility concerns and reducing build complexity. Thermal coatings on the lobe surfaces reduce friction and wear, extending service life under sustained high-RPM operation—critical for truck engines subject to towing and load-carrying demands.

This camshaft suits truck builders, hot rodders, and performance enthusiasts upgrading Gen 3 and Gen 4 LS truck engines for increased horsepower and torque delivery. Installation pairs easily with upgraded intake manifolds, port work, and ECU tuning to unlock 50–100+ additional horsepower while retaining stock valve train architecture. The Stage 2 grind is forgiving enough for street-driven trucks yet aggressive enough to justify dyno testing post-installation—allowing you to quantify power gains before and after ancillary modifications. Compatibility remains unchanged across all Gen 3/4 LS variants, making this a bolt-in upgrade path for anyone serious about maximizing their LS truck platform without a complete engine redesign.
