GEN 3 & 4 Torque Truck Cam

The GEN 3 & 4 Torque Truck Cam from Brian Tooley Racing is a purpose-built hydraulic roller camshaft engineered for GM LS-series engines in full-size trucks and performance applications. This cam delivers the torque band characteristics that truck owners demand—strong mid-range response and reliable power delivery across real-world driving conditions. Whether you're building a stock truck platform for daily driving or modifying a performance engine, this camshaft provides the mechanical foundation for increased horsepower and torque without requiring complex engine management tuning or aggressive mechanical specifications.

The GEN 3 & 4 Torque Truck Cam features 0.510-inch lift on both intake and exhaust, with a 202-degree duration rating and a 111-degree lobe separation angle (LSA) that optimizes the overlap window for truck-style torque characteristics. The hydraulic roller design provides reliable valve actuation with reduced friction compared to flat-tappet designs, while the 2300–6200 RPM power band ensures broad usability from idle through highway cruising speeds. Brian Tooley Racing's engineering focuses on practical performance: this cam minimizes idle roughness and maintains stock transmission compatibility, making it ideal for street-driven trucks that need genuine power gains without sacrificing drivability or requiring supporting modifications.

Truck builders, performance shops, and engine rebuilders select the GEN 3 & 4 Torque Truck Cam for naturally aspirated LS engine builds targeting Gen III and Gen IV truck platforms from General Motors. Installation requires basic pushrod engine assembly knowledge and proper valve-to-piston clearance verification during engine assembly. This camshaft pairs effectively with stock or mildly ported cylinder heads, factory intake manifolds, and standard fuel delivery systems, making it an efficient first-stage upgrade for owners seeking tangible torque improvement without expensive component changes or extended dyno tuning sessions.
