GEN 3 & 4 LS Stage 4 V2 Truck Cam

The GEN 3 & 4 LS Stage 4 V2 Truck Cam from Brian Tooley Racing is purpose-built for serious LS engine builders and truck enthusiasts who demand reliable, repeatable performance gains without sacrificing everyday drivability. This cam profile sits in the sweet spot between street and strip duty, engineered specifically for Gen 3 and Gen 4 LS platforms that feed large-displacement, naturally aspirated power seekers.

The Stage 4 V2 designation reflects Brian Tooley Racing's iterative refinement of cam lobe geometry, lift curves, and duration for optimal valve event timing on modern LS cylinder heads. This profile delivers aggressive lift and duration values that maximize volumetric efficiency while maintaining stable valve train dynamics at higher RPM. The V2 revision incorporates feedback from real-world dyno and street testing, resulting in improved power delivery and reduced tuning sensitivity compared to earlier generations.

This cam is ideal for LS truck builds running aftermarket intake manifolds, heads, and tuning—whether you're aiming for 500 naturally aspirated horsepower or enhancing your truck's performance without radical valve timing. Brian Tooley Racing's precision grinding and quality control ensure consistent lobe profiles across the entire camshaft, critical for balanced combustion and reliable long-term durability.
