COMP Cams 1983-16, Max-Lift BSR LS7 Shaft Rockers System,

1.8 Rocker Ratio, Suits LS7 type heads only. 

This pair of Comp Cams, Max-Lift BSR Shaft Mount Rockers for Raised Rectangle Port LS7 engines is a bolt-in rocker upgrade that requires no machine work to install. Clears factory valve covers while greatly increasing valvetrain rigidity.

COMP Cams introduces another industry first with their Max-Lift BSR shaft rocker systems, a bolt-in bushed shaft rocker system that increases valve train 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 valve train stiffness and reduce deflection under extreme loads. The increased valve train stiffness created the BSR rocker system allows your existing cam to act like a larger camshaft by transferring more of the motion to the valve or the use of more aggressive, higher lift cams without losing control of the valve train. Take complete control of your valves with the COMP Cams 1983-16 Max-Lift BSR shaft rocker system.
