COMP CamsA? expands upon its Max-Lifta*? BSR Shaft Rocker Systems to include aftermarket LS3-style cylinder heads. This new bolt-in, bushed shaft rocker system is specifically designed for aftermarket LS3 heads where valve geometry is different from the stock configuration.
By tying all eight rockers onto a single shaft, the BSR Series of rockers improves valve train dynamics by increasing valve train stiffness. Replacing the high-Hertz loading needle bearings with tri-layer bushings reduces deflection, allowing for increased rigidity and decreased rocker pad wear. The plasma-nitride finish minimizes friction and increases durability, while provisions for optional pressurized oiling further improve longevity and performance. The increased valve train stiffness provided by the COMP Cams Max-Lift BSR Shaft Rocker System 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. The Max-Lift BSR Shaft Rocker System ensures the rocker pad and valve tip remains parallel through the contact sweep, allowing the rocker to safely sweep up to .675a*? valve lift. The Max-Lift BSR Shaft Rockers System for aftermarket LS3-style heads will fit RHS 54550 Pro Elite LS3, Edelbrock Victor CNC LS3, Trick Flow 255 LS3, AFR Mongoose LS3, and Mast Black Label LS3.
Max-Lift BSR Shaft Rockers for Aftermarket LS3-style cylinder heads single-shaft design increases valve train stiffness, durability, and lift to .675", while improving dynamics. Tri-layer bushings and plasma-nitride finish reduces friction.
