Comp Cams BSR Shaft Rocker System - (GM LS7 Heads)
Comp Cams introduces another industry first with their Max-Lift "BSR" Shaft Rocker Systems, a bolt-in bushed shaft rocker system that increases valvetrain stiffness helping your engine 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 valvetrain stiffness and reduce deflection under extreme loads.
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 valvetrain 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.
Take complete control of your valves with the Comp Cams Max-Lift BSR shaft rocker system.
