Max Lift BSR 1.70:1 Shaft Rocker KitSuit AFR & RHS LS3 HeadsBrand: COMPPart Number: CO1980-16Description: COMP Cams introduces another industry first with their Max-Lift BSR Shaft Rocker Systems, a bolt-in bushed shaft rocker system forGM LS applications that increases system stiffness andallows LS platforms to achievehigher levels of performance.
By tying all eight rocker arms togetheron a single shaft that fits inthe stock rocker stand, COMP Cams has found a way to improve valve train dynamics, increase valve train stiffnessand reduce deflection. The useof a tri-layer bushing insteadof 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 tofurther improve rocker arm durability and performance.
The increased valve train stiffness provided by the COMPCams Max-Lift BSR Shaft RockerSystems 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 useof higher lift, more aggressive camshafts before the valve train goes out of control.
- Fully assembled with proven stock rocker bodies
- Bolts into stock rocker stand
- Better stabilityallows use of more aggressive camshafts
- Plasma nitride finish minimizes friction and increases durability
