LS1ShaftRockers
COMP Cams is proud to announce another industry first: a bolt-in-ready Bushed Shaft Rocker System for GM LS engines. Thanks to innovative engineering, this patent pending Bushed Shaft Rocker System increases valve train stability and durability while decreasing deflection and providing bolt-in convenience for LS1, LS3 and LS7 cylinder heads. The COMP Cams Bushed Shaft Rocker System improves valve train stability and durability by securing all eight rocker arms onto a single rocker shaft. Thin tri-layer rocker arm bushings reduce rocker arm deflection and eliminate the high Hertz loading that can occur in needle bearing equipped rockers. Reduced rocker deflection increases valve train stiffness, ensuring that your LS is more efficient and durable under high loads. COMP Cams engineers worked to ensure long-term valve train durability by perfecting rocker to valve stem geometry and provisioning for supplementary pressurized oiling via threaded ends on the rocker shafts. Additionally, each rocker shaft is Plasma Nitrided, further increasing the system’s durability even when used with aggressive solid roller valve trains. The COMP Cams Bushed Shaft Rocker System for GM LS delivers high-level valve train stability, precise fitment, truer valve train geometry and increased load-bearing capacity in a package that is ready to bolt in that requires no machine work.
This pair of Max-Lift BSR Shaft Mount Rockers for Cathedral Port LS engines is a bolt-in rocker upgrade that requires no machine work to install. Clears factory valve covers while greatly increasing valvetrain rigidity.

Rocker Arms, Shaft Mount, Steel, 1.7 Ratio, Chevy, LS, Kit
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 Max-Lift BSR shaft rocker system.
