COMP Cams Max-Lift BSR Shaft Rocker Kit for 2006-2015 Chevrolet Camaro and Corvette (LS7) - 1983-16

Fits 2006-2015 Chevrolet Camaro Z/28 and Corvette Z06/427 models equipped with the 7.0L LS7 engine.

The COMP Cams Max-Lift BSR Shaft Rocker Kit (MPN 1983-16) is a bolt-in valvetrain solution designed to increase stability and durability in high-performance LS7 applications. By securing all eight rocker arms onto a single, rigid rocker shaft, this system significantly reduces deflection compared to individual pedestal-mount rockers. This increased stiffness ensures more efficient valve operation and better performance under heavy high-RPM loads.

This patent-pending Bushed Shaft Rocker (BSR) system replaces traditional needle-bearing rockers with thin tri-layer bushings. This design eliminates the high Hertz loading associated with needle bearings, preventing potential bearing failure and protecting your engine. Each rocker shaft is Plasma Nitrided for superior wear resistance and features threaded ends to allow for supplementary pressurized oiling, ensuring long-term reliability even with aggressive solid roller valvetrains.

• Increased Stability: Single-shaft design minimizes rocker arm deflection and improves valvetrain geometry.
• Bushed Design: Tri-layer bushings replace needle bearings to handle higher load-bearing capacities.
• Durable Finish: Plasma Nitrided rocker shafts for maximum surface hardness and longevity.
• Bolt-In Installation: Designed for LS7 cylinder heads; requires no machine work for fitment.
• Part Number: 1983-16
