The COMP Cams Max-Lift BSR Shaft Rocker System for GM Gen V/LT engines increases valve train stiffness and strength, for improved valve train dynamics, durability and RPM capability.
By tying pairs of rocker arms together, 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 reduces deflection, which then allows for increased rigidity and decreased rocker pad wear. 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 remain parallel through the contact sweep, allowing the rocker to safely sweep up to .675” valve lift. Available for GM GEN V LT1/LT2/LT4/LT5/L86 engines, the COMP Cams Max-Lift BSR Shaft Rocker System ships fully assembled for an easy, bolt-on installation. Does NOT fit GM Gen V L83 (5.3L) cylinder heads.
