Control Your LS/LT Valvetrain and Unleash More Power with COMP Cams Max-Lift BSR Shaft Rocker Systems
Big camshafts, high valve lift, and serious RPM demand a valvetrain that stays under control. COMP Cams Max-Lift BSR Shaft Rocker Systems are engineered to keep your LS valvetrain stable when you’re gunning for maximum horsepower.
Unlike conventional individual rocker arms, the Max-Lift BSR design ties the rockers together with a rigid shaft assembly that reduces flex and deflection under extreme loads. The result is more consistent valve motion and improved valvetrain stability when running aggressive cams, high spring pressures, and high RPM.
Other features include:
• Precision-machined aluminum rocker bodies
• Premium needle bearings
• Bushed rocker shafts
• Optimized geometry for consistent valve motion
• 1.7 or 1.8 ratio (depending on application)
• Black nitride finish
• Includes mounting hardware where required
COMP Cams Max-Lift BSR Shaft Rocker Systems are available for GM LS7, LS3/L92, and LT engines.
