COMP Cams Max-Lift BSR Shaft Rocker Kit Chevy LS3

The COMP Cams Max-Lift BSR Shaft Rocker Kit for Chevy LS3 is a high-performance, bolt-in-ready Bushed Shaft Rocker System designed for GM LS engines. Featuring innovative engineering, this patent-pending system enhances valve train stability and durability by securing all eight rocker arms onto a single rocker shaft. The kit includes thin tri-layer rocker arm bushings that reduce deflection and eliminate high Hertz loading common in needle bearing rockers. Plasma nitrided rocker shafts further increase durability, especially when used with aggressive solid roller valve trains. This system improves valve train stiffness, ensuring more efficient operation under high loads, and provides precise valve train geometry for optimal performance.

Designed for LS1, LS3, and LS7 cylinder heads, this system offers a direct bolt-in upgrade that requires no machine work. It is suitable for street, track, or high-performance applications where valve train stability and durability are critical. The kit delivers increased load-bearing capacity and long-term reliability, making it an ideal choice for enthusiasts seeking a high-quality, easy-to-install upgrade to improve engine performance and longevity.
