COMP Cams Max-Lift BSR Shaft Mount Steel Rocker Arm Kit - 1.80 Ratio - GM GenV LT-Series Orbital Polisher 3 AN Male to MaleBy 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
