• Anti-rust finish for added surface protection
• Self-aligning design
• Shaft-mounted configuration
• Standard replacement grade

Detailed Description

Melling MR-944 rocker arms are engineered for domestic and import engine applications where stock-style replacement parts are needed. This rocker arm uses cast steel material, a roller tip design, and shaft mounting to match the requirements of specific OEM valve train setups. The self-aligning design helps maintain proper rocker positioning during operation, while the anti-rust finish adds protection against surface corrosion. This part cross-references 180-1325 and ER9114 for the same application.

For buyers servicing a Ford Mustang, Ford Ranger, or Ford Explorer engine, the MR-944 provides a direct-fit replacement option within the listed stock applications. It is also listed for Ford Explorer Sport Trac, Mercury Mountaineer, and Ford GT applications where the same rocker arm specification is required. The MR-944 part number should be verified against the engine’s original rocker arm design before installation.

What It Is Used For

• Replacing worn rocker arms in a valve train rebuild
• Restoring proper valve actuation and motion transfer
• Addressing noise caused by rocker arm wear or damage
• Correcting valve train instability from mismatched components
• Supporting stock engine rebuild specifications

Installation Notes and Tips

Confirm shaft-mounted, self-aligning rocker arm requirements before installation. Inspect related valve train components during service and replace worn parts as needed to maintain correct geometry. Melling recommends installing new rocker arms and related components during every engine rebuild for consistent performance and long engine life.

Quality Assurance

Melling states that its rocker arms are manufactured using controlled materials and processes selected for engine service applications. The Stock line covers replacement parts for domestic and import engines, and the MR-944 follows a standard replacement specification for listed fitments.
