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. If you're modifying a truck with LS power and want measurable torque and horsepower across the RPM band without radical valve timing, this is the cam profile you've been researching.

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. 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 in turbocharged or supercharged applications.

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 laying groundwork for forced induction. Installation requires proper valve lash adjustment and tuning optimization to extract full potential; working with a knowledgeable LS tuner will ensure your engine realizes peak performance and reliability. The GEN 3 & 4 LS Stage 4 V2 Truck Cam is compatible with LS1, LS2, LS3, LS6, L98, and truck-block variants using conventional hydraulic roller lifters. Verify your specific engine generation and cylinder head configuration before purchase to ensure proper fit and valve-to-piston clearance with your compression ratio and piston design.
