Single bolt rocker arm designs, such as that found in LS1, LS3 and LS7 engines, can cause deflection in the valve train. Furthermore, needle bearings, common to the trunnions found in these applications, can suffer from a high Hertz loading. By tying all eight rocker arms together, the COMP Cams® Max-Lift BSR Shaft Rocker Systems™ increase valve train stiffness and reduces deflection and because it incorporates tri-layer bushings instead of needle bearings it also further reduces deflection and eliminates the high Hertz loading.
The COMP Cams® Max-Lift BSR Shaft Rocker Systems™ allows for the use of a higher lift, more aggressive camshaft or can make your current cam function more efficiently by better stabilizing your valve train and reducing deflection while bolting right up to OEM rocker arm mounting points. The system also includes provisions for optional pressurized oiling and a plasma nitride finish for minimized friction and maximum durability.
