GEN 3 & 4 LS Stage 4 V2 Truck Cam

The GEN 3 & 4 LS Stage 4 V2 Truck Cam from Brian Tooley Racing delivers measurable power gains and drivability improvements for Gen III and Gen IV LS-powered trucks. Designed for serious enthusiasts who demand more than bolt-on horsepower, this camshaft targets the sweet spot between street performance and aggressive lift characteristics. Whether you're building a weekend warrior or upgrading an existing LS platform, the Stage 4 V2 specification provides the aggression needed to unlock true engine potential without sacrificing everyday usability.

Brian Tooley Racing's engineering focuses on optimized valve lift, duration, and lobe separation angle to maximize cylinder filling and scavenging efficiency across the RPM band. The Stage 4 V2 profile sits higher up the performance ladder than milder grinds, demanding supporting modifications like quality valve springs, pushrods, and potentially lifter upgrades to handle increased loads safely. Precision manufacturing tolerances ensure consistent performance across the entire production run, critical for maintaining reliability when running elevated spring pressures and higher boost levels typical of forced-induction LS builds.

This camshaft fits both naturally aspirated and boosted Gen III and Gen IV LS engines, making it ideal for truck owners planning comprehensive power builds. Installation requires proper valve lash adjustment and verification of pushrod geometry, tasks best handled by experienced builders or equipped shops familiar with LS architecture. Pair the GEN 3 & 4 LS Stage 4 V2 Truck Cam with matching spring kits, quality fuel management, and cam-synchronized tuning to realize maximum horsepower and torque gains while maintaining long-term engine durability.
