LS1/LS2 Shaft Rocker Kit Assembled

The LS1/LS2 Shaft Rocker Kit Assembled by Brian Tooley Racing is engineered for serious LS engine builders and street/strip enthusiasts who demand reliable, high-rpm valvetrain geometry. Whether you're upgrading a stock LS1 or maximizing performance on a heavily modified LS2, this assembled kit delivers the precision rocker arm ratio and durability needed to support aggressive cam profiles and elevated engine speeds. Brian Tooley Racing has built its reputation on OEM-quality manufacturing standards, making this kit an ideal choice for those who refuse to compromise on valvetrain stability.

Shaft rocker systems distribute load across a hardened steel shaft rather than individual rocker studs, dramatically reducing deflection and improving valve actuation consistency at high RPM. The assembled configuration saves critical build time by arriving pre-fitted and ready for installation, with all internal components—rocker arms, bushings, and retention hardware—factory-verified for proper clearance and alignment. This design maintains superior oil flow characteristics compared to stud-mounted alternatives, critical for extended durability during sustained high-boost or naturally aspirated applications where rocker arm temperatures climb significantly.

This kit fits both LS1 (1997–2004 Corvette, Camaro, Firebird) and LS2 (2005–2007 Corvette, 2006–2007 GTO) platforms, making it a versatile solution for first and second-generation LS swaps. Installation requires proper valve lash adjustment and confirmation that your rocker arm geometry clears any aftermarket intake manifolds or cylinder head porting work. Weighing 11.45 lbs, the complete assembled package ships ready for bolt-on installation, allowing you to focus on final tuning rather than tedious rocker arm assembly and preload setup.
