What It Helps Address

• Worn rocker arm contact surfaces in the valve train
• Excess friction from a non-roller design
• Corrosion on exposed valve train components
• Valve train noise caused by worn or damaged hardware
• Restoration needs during an engine rebuild

Installation Notes and Tips

Use the MR-1341 only where the engine calls for a roller, self-aligning rocker arm with bolt mounting. Verify the engine’s OEM rocker arm design before installation, especially on applications with VIN code or stock-specific notes. Melling recommends replacing rocker arms and related components during a full engine rebuild to maintain long-term performance.
