Description

The Brian Tooley Racing LS3 Stage 4 V2 is BTR’s most aggressive naturally aspirated LS3 camshaft — and this kit gives you everything needed to install it right and support it properly from day one. The Stage 4 V2 was purpose-built for builders chasing 500+ wheel horsepower from a stock displacement 6.2L LS3 with proper bolt-on supporting modifications, all while retaining the reliability and durability that BTR is known for. With a 233°/24X° duration profile, .636″/.636″ valve lift, a 111° LSA, and a 3,500–7,000 RPM operating range, this cam delivers strong top end power that keeps climbing all the way to redline. 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 4 V2 takes it as far as a naturally aspirated stock displacement engine can go.

This kit pairs the LS3 Stage 4 V2 with a complete, matched valvetrain package built to support its aggressive .636″/.636″ lift profile at every RPM. The .660″ dual valve springs with steel retainers and locks deliver the seat and open pressures needed for reliable high-RPM operation at this lift level — a serious spring package for a serious cam. Steel retainers and locks 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 max effort cam like the Stage 4 V2, 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 6.2L LS3-based engines. Stock torque converters work perfectly fine in the 5th Gen Camaro SS, Corvette C6, and Pontiac G8 GT/GXP with this cam — making it one of the most accessible max effort LS3 grinds available. A professional tune is required for both automatic and manual applications. Measuring piston-to-valve clearance prior to installation is always recommended. Big power. Broad powerband. Built for the street.

This kit is built around a complete, matched valvetrain package that leaves nothing to chance.
