COMP Cams Max-Lift BSR Shaft Rocker Kit for Chevy LS3 Engines - Part 1982-16

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 Rectangle Port (LS3/L92) LS engines is a bolt-in rocker upgrade that requires no machine work to install. Clears factory valve covers while greatly increasing valvetrain rigidity. See 1981-16 for LS1/2/6. See 1983-16 for LS7.

Upgrade your Chevy LS3 engine with the COMP Cams Max-Lift BSR Shaft Rocker Kit, part number 1982-16, designed for exceptional valve train stability and durability. This bolt-in-ready system features a patent-pending Bushed Shaft Rocker design that securely mounts all eight rocker arms onto a single shaft, eliminating the need for extensive machine work. Engineered to fit directly onto factory components, the system maintains proper valve-to-rocker geometry while increasing load capacity for high-performance applications.

The system utilizes thin tri-layer rocker arm bushings that significantly reduce rocker arm deflection and eliminate high Hertz loading common in needle bearing rockers. This reduction in deflection enhances valve train stiffness, leading to improved efficiency and long-term durability, especially under high loads typical of aggressive cam profiles. Additionally, each rocker shaft undergoes Plasma Nitriding treatment, further boosting wear resistance and overall longevity even when used with solid roller valve trains.

Designed for seamless installation, this system clears factory valve covers and requires no machining or modifications. It is compatible with a variety of GM LS engines, including the LS3, and is suitable for applications demanding increased valvetrain rigidity and precise valve control. Whether you’re building a street performance or a race engine, the COMP Cams Bushed Shaft Rocker System offers reliable performance with an easy bolt-in upgrade that ensures your LS engine maintains optimal valve train geometry and load-bearing capacity.
