COMP Cams Max-Lift BSR shaft rocker system is engineered for aftermarket LS3-style cylinder heads, providing a single-shaft, bushed rocker setup that increases valve-train stiffness and allows up to .675" valve lift. Tri-layer bushings replace needle bearings to reduce deflection while a plasma-nitride finish lowers friction. The system fits several aftermarket LS3 heads and supports higher-lift cams reliably.
