Detailed Description

The Melling MPR-73 is an engine push rod engineered for stock replacement use in classic Ford and Mercury engines. Its 7.967-inch length, 0.312-inch diameter, and matched tip design help maintain proper valve train geometry when replacing worn or damaged push rods. This part number is used across applications such as Ford Fairlane, Ford Thunderbird, and Mercury Monterey, making it a practical choice for restoration and maintenance work. Melling recommends replacing push rods during service to preserve correct valve train performance, and the MPR-73 is part of the brand’s broader OE and performance push rod lineup. This part cross-references Monroe Shocks & Struts (e.g., 74-6073, PR-73) for the same application.

What It Is Used For

• Replacing bent or worn push rods in stock engines
• Restoring correct valve train geometry
• Addressing valvetrain noise caused by damaged components
• Supporting proper lifter and rocker arm operation
• Maintaining consistent engine performance in classic Ford and Mercury builds

Installation Notes and Tips

Verify push rod length, tip style, and diameter before installation. The MPR-73 uses a ball-end lower tip and cup-end upper tip, so it should be matched to the original valvetrain design. Inspect related valvetrain components for wear before assembly, and replace damaged push rods rather than reusing them.

Quality Assurance

Melling builds this push rod to stringent manufacturing specifications using quality materials and processes. The part is made in the USA and is part of Melling’s standard replacement offering for OEM-style service.
