The GMC Sierra Rocker Arm Kit by COMP Cams - Max-Lift BSR Shaft Rocker System is a must-have upgrade for your 2011-2016 GM LS engines. Designed to enhance engine performance, this system is crafted for the automotive enthusiast seeking to improve their vehicle's valve train stability and efficiency. The Max-Lift BSR Shaft Rocker System combines precision engineering with top-tier materials, providing an all-in-one solution that ensures ease of installation and superior engine functionality.

Engineered for seamless integration, this kit is tailored to work with GM LS1, LS3, and LS7 cylinder heads, fitting perfectly without the need for modifications. The innovative design of this system involves securing all eight rocker arms onto a single rocker shaft. This configuration not only increases valve train stability and durability but also decreases deflection. The thin tri-layer rocker arm bushings are a notable feature, minimizing deflection and eliminating the high Hertz loading typical of needle-bearing rockers. Additionally, the rocker shafts are plasma nitrided, enhancing their durability, especially under high load conditions.
