CO1981-16 - MAX LIFT BSR SHAFT ROCKER KIT

Suit GM LS1, LS2 & LS6

Part Number: CO1981-16

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.
Fully assembled with proven stock rocker bodies
Bolts into stock rocker stand
Better stability allows use of more aggressive camshafts
Plasma nitride finish minimizes friction and increases durability
Available for LS1/LS3/LS7 applications
