COMP Cams 1983R-1 Bushed Offset Rocker Arm for LS7 Max-Lift BSR System

The COMP Cams 1983R-1 is an individual offset bushed rocker arm designed specifically for LS7 cylinder head applications. This rocker arm is a precision-engineered service component of COMP Cams' Max-Lift BSR (Bushed Shaft Rocker) System, featuring the offset geometry required for proper valve train alignment on LS7 raised rectangle port cylinder heads.

Key Features:

• Offset design engineered specifically for LS7 cylinder head geometry and 1.8 rocker ratio applications
• Tri-layer bushing construction replaces conventional needle bearing trunnions to reduce deflection and eliminate high Hertz loading under extreme valve train loads
• Plasma nitride finish minimizes friction and maximizes wear resistance for long-term durability
• Bolt-in compatibility with the COMP Cams Max-Lift BSR shaft rocker system — installs into stock rocker stands with no machining required
• Provisions for pressurized oiling via threaded shaft ends for enhanced lubrication and rocker arm longevity
• Fully assembled rocker body using proven stock-style rocker architecture

The bushed shaft rocker design improves valvetrain stiffness by tying rocker arms to a single shaft, allowing existing camshafts to transfer more lobe lift directly to the valve. This results in improved valvetrain dynamics, reduced deflection under load, and the ability to run more aggressive camshaft profiles with confidence. COMP Cams recommends installing new pushrods when fitting any new rocker arm to ensure proper mating surface contact and protect your rocker arm warranty.
