Key Features & Benefits
- Genuine GM OEM Replacement: This Genuine GM rocker arm is a factory-style replacement for compatible LS7 cylinder head applications requiring GM part number 12579617. It is a useful service part when repairing the original valvetrain or replacing an individual worn or damaged rocker arm.
- LS7 Straight Exhaust Rocker Arm: This is the straight exhaust rocker arm used for LS7 head applications. It is intended for the exhaust side of the valvetrain where the correct rocker arm style and position are required for proper factory-style operation.
- 1.8 Rocker Arm Ratio: The rocker arm features the supplied 1.8 ratio for LS7 applications. Matching the correct rocker ratio is important when servicing the LS7 valvetrain, replacing damaged components, or maintaining the intended factory rocker arm geometry.
- Fits LS7 Heads Only: This rocker arm is designed specifically for LS7 heads and should be used only in the listed LS7 cylinder head applications. It is a targeted replacement part for LS7 engine service rather than a universal LS rocker arm.
- Ideal for LS7 Valvetrain Service: This new OEM rocker arm is a practical replacement during cylinder head repair, valve spring service, rocker arm inspection, engine rebuilds, or valvetrain refresh work. It allows customers to replace the specific exhaust rocker arm needed without purchasing a full rocker arm set.
