BSR Shaft Rocker System Max-Lift GM LS7

The BSR Shaft Rocker System Max-Lift for GM LS7 by COMP CAMS is a precision-engineered rocker arm assembly designed for serious LS engine builders and track-focused enthusiasts who demand maximum valve lift capability. This system replaces factory rocker arms to unlock additional lift travel, enabling custom camshaft profiles that stock rockers may not accommodate. Built specifically for LS7 engines, this assembly is essential for those pursuing aggressive cam profiles, increased airflow, and peak power output beyond factory limitations.

The shaft rocker design delivers superior geometry and valvetrain stability compared to individual stamped rockers, maintaining precise valve timing and lift across the entire RPM range. COMP CAMS engineered this system with hardened steel components and optimized contact surfaces to handle the demands of high-rev, high-lift operation without accelerated wear or valve float. The Max-Lift designation indicates this assembly is calibrated to support lift specifications exceeding factory LS7 rocker capabilities, making it suitable for cam grinds in the 0.600+ inch lift range.

The robust shaft construction distributes load more effectively than pedestal-mounted alternatives, reducing flex and ensuring consistent valve actuation. This translates directly to more responsive throttle control and measurable horsepower gains. The BSR Shaft Rocker System Max-Lift is ideal for high-performance builds and those looking to maximize their LS7 engine's potential.
