COMP Cams® Max-Lift BSR Shaft Rocker Systems™ for GM LS Applications



Memphis, TN – COMP Cams® introduces another industry first with their Max-Lift BSR Shaft Rocker Systems™, a bolt-in, patent-pending, bushed shaft rocker system for GM LS applications that increases system stiffness and allows LS platforms to achieve a higher level of performance.

By tying all eight rocker arms together on a single shaft that fits in the stock rocker stand, COMP Cams® has found a way to improve valve train dynamics, increase valve train stiffness and reduce deflection. The use of a tri-layer bushing instead of needle bearings also reduces deflection and eliminates the high Hertz loading that is present in needle bearing trunnions, for more rigidity and durability. In an industry first, COMP Cams® included provisions for optional pressurized oiling to further improve rocker arm durability and performance.

The increased valve train stiffness provided by the COMP Cams® Max-Lift BSR Shaft Rocker Systems™ makes the same camshaft perform like a slightly larger camshaft as more of the lobe lift is transferred directly to the valve train instead of being absorbed by deflection in the cylinder head and single-bolt rocker mounting design. The system will also allow the use of higher lift, more aggressive camshafts before the valve train goes out of control.

Available for LS1, LS3 and LS7 applications, the COMP Cams® Max-Lift BSR Shaft Rocker Systems™ features a plasma nitride finish that minimizes friction and increases durability.
