COMP Cams Max-Lift BSR Shaft Rocker Kit for GM LS7 Engines – Part Number 1983-16

COMP Cams is proud to announce another industry first: a bolt-in-ready Bushed Shaft Rocker System for GM LS engines. Thanks to innovative engineering, this patent pending Bushed Shaft Rocker System increases valve train stability and durability while decreasing deflection and providing bolt-in convenience for LS1, LS3 and LS7 cylinder heads. The COMP Cams Bushed Shaft Rocker System improves valve train stability and durability by securing all eight rocker arms onto a single rocker shaft. Thin tri-layer rocker arm bushings reduce rocker arm deflection and eliminate the high Hertz loading that can occur in needle bearing equipped rockers. Reduced rocker deflection increases valve train stiffness, ensuring that your LS is more efficient and durable under high loads. COMP Cams engineers worked to ensure long-term valve train durability by perfecting rocker to valve stem geometry and provisioning for supplementary pressurized oiling via threaded ends on the rocker shafts. Additionally, each rocker shaft is Plasma Nitrided, further increasing the system’s durability even when used with aggressive solid roller valve trains. The COMP Cams Bushed Shaft Rocker System for GM LS delivers high-level valve train stability, precise fitment, truer valve train geometry and increased load-bearing capacity in a package that is ready to bolt in that requires no machine work. This pair of Max-Lift BSR Shaft Mount Rockers for Raised Rectangle Port LS7 engines is a bolt-in rocker upgrade that requires no machine work to install. Clears factory valve covers while greatly increasing valvetrain rigidity. See 1982-16 for LS3/L92. See 1981-16 for Cathedral Port LS engines.

Upgrade your GM LS7 engine with the COMP Cams Max-Lift BSR Shaft Rocker Kit, designed for bolt-in installation without the need for machine work. This high-performance rocker system enhances valve train stability and durability by securely mounting all eight rocker arms onto a single, precision-engineered shaft. The innovative tri-layer rocker arm bushings significantly reduce deflection and eliminate high Hertz loading typically associated with needle bearing rockers, resulting in improved valve train stiffness and increased efficiency under high loads.
Constructed with Plasma Nitrided rocker shafts, this system offers exceptional durability and resistance to wear even when paired with aggressive solid roller valve trains. The system's precise fitment and optimized valve-to-rocker geometry promote truer valve operation, which translates to better performance and longer service life. Designed specifically for LS7 engines, this kit clears factory valve covers, providing a clean look while greatly increasing valvetrain rigidity. Its robust design ensures enhanced load-bearing capacity, making it a reliable upgrade for high-performance applications.
Suitable for 2006-2013 Chevrolet Corvette models, this kit delivers a straightforward installation process, making it an ideal choice for enthusiasts seeking a reliable, bolt-in valvetrain upgrade.
