NEW Comp Cams Max-Lift BSR Shaft Mount Rocker System; LS7, 1.8 Ratio, Set

COMP Cams® introduces another industry first with their Max-Lift BSR Shaft Rocker Systems™, a bolt-in bushed shaft rocker system for GM LS applications that increases system stiffness and allows LS platforms to achieve higher levels 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 a first for the LS market, provisions are included 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, 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.
