Description

The Brian Tooley Racing LS3 Stage 1 V2 is the perfect entry point into serious LS3 performance — and this kit gives you everything needed to install it right and support it properly from day one. The Stage 1 V2 was purpose-built for builders who want more power and torque across the entire RPM range without sacrificing the smooth, predictable power curve that makes a car genuinely enjoyable to drive every single day. With dyno-proven gains of 56+ rear wheel horsepower and 24+ lb-ft of torque, a factory torque converter friendly design, and a smooth powerband that works equally well for daily commuters and weekend warriors, this is the cam that does everything right without demanding anything extra from your drivetrain. The 6.2L LS3 is one of the most popular and capable engines in the entire GM lineup — beloved by the LS swap community and performance builders alike for its power potential, lightweight aluminum block, and incredible aftermarket support — and the Stage 1 V2 extracts more of what it already has.

This kit pairs the LS3 Stage 1 V2 with a complete, matched valvetrain package built to support it at every RPM. The .660″ dual valve springs with steel retainers deliver the seat and open pressures needed for reliable high-RPM operation at this cam’s lift level — providing the valvetrain stability a performance cam demands without going overboard for this application. Steel retainers are included for a complete, professional spring installation with no additional parts needed. The hardened chromoly pushrods at 7.400″ length and 0.080″ wall thickness eliminate the flex that stock pushrods cannot handle under a performance cam, and 16 premium valve stem seals ensure a clean, oil-tight build from day one. Every component in this kit is selected to work together seamlessly so you can focus on the build — not the sourcing.

This kit is built specifically for 2008–2015 GM 6.0L and 6.2L LS-based engines including LS3, L99, L76, and L77.

This cam is designed to work with factory torque converters making it an ideal daily driver upgrade. Measuring piston-to-valve clearance prior to installation is always recommended. Big power. Broad powerband. Built for the street.
