Description

The Brian Tooley Racing BTR LS3 Stage 2 V2 delivers dyno-proven gains of 62+ rear wheel horsepower and 22+ lb-ft of torque on the 6.2L LS3 platform — purpose-built to extract maximum naturally aspirated power from the Camaro SS, Corvette C6, and G8 GXP. Featuring 221/24X duration at .050″, .624″/.624″ valve lift, and 112 LSA, the Stage 2 V2 turns an already impressive 6.2L into something that demands attention at every RPM — firing up with an aggressive choppy idle that lets everyone nearby know this LS3 has been properly built. BTR camshafts are designed in house, Spintron tested, and engine dyno proven before they ever reach a customer — each cam born from its own specific cam core with no generic cores used — resulting in more average torque, higher peak power, and maximum depth heat treatment for long-term reliability. This complete kit includes everything a professional installer would spec — BTR LS3 Stage 2 V2 camshaft, .660″ dual valve spring kit with steel retainers and locks, hardened chromoly pushrods at 7.400″ length and 0.080″ wall thickness, premium valve stem seals, and a premium LS rocker arm trunnion upgrade kit. One order, one shipment, zero guesswork. Lifetime warranty if installed by a certified machinist.

The .660″ dual valve spring kit with steel retainers and locks delivers the seat and open pressures needed for reliable high-RPM operation at the LS3 Stage 2 V2’s .624″/.624″ lift level — a serious spring package for a serious cam with no additional parts needed for a complete professional spring installation. The hardened chromoly pushrods at 7.400″ length and 0.080″ wall thickness are built for the demands of a high lift performance cam like the LS3 Stage 2 V2 — stock pushrods flex under load and these don’t. The premium LS rocker arm trunnion upgrade kit converts your stock LS3 rocker arms into captured roller bearing rocker arms — eliminating the factory failure point that has caused catastrophic engine damage in countless LS builds. This kit eliminates the need to piece together your LS3 cam swap from multiple sellers — the cam, springs, retainers, locks, pushrods, valve stem seals, and trunnion upgrade kit are all spec’d to work together and ship together. Brian Tooley Racing camshafts are designed and manufactured in the USA — backed by extensive Spintron testing and in-house dyno development.

This is not a subtle upgrade — it is a complete transformation of what your 6.2L LS3 is capable of. Big power. Broad powerband. Built for the street.
