COMP Cams Max-Lift BSR Shaft Rocker Kit for Select 2007-2017 Cadillac, Chevrolet, GMC, Hummer, and Pontiac (LS3)

Fits select 2007-2017 Cadillac, Chevrolet, GMC, Hummer, and Pontiac models equipped with LS3-style cylinder heads. This COMP Cams Max-Lift BSR (Bushed Shaft Rocker) System provides a bolt-in solution to increase valvetrain stability and durability without the need for custom machining.

By mounting all eight rocker arms onto a single, rigid rocker shaft, the BSR system significantly reduces deflection compared to individual stud-mounted rockers. The kit replaces traditional needle bearings with thin tri-layer bushings, which eliminate high Hertz loading and provide a larger surface area for load distribution. To ensure longevity under high-load or aggressive solid roller applications, each shaft is plasma nitrided and includes threaded ends for supplementary pressurized oiling.
