Detailed Description

Melling MPR-31 is a stock-style engine push rod intended for classic GM valve train service where correct length, tip design, and material consistency matter. The welded steel construction and standard replacement grade support accurate geometry in engines that use this push rod specification. For buyers restoring or maintaining Chevrolet and GMC engines from the 1942-1961 range, the MPR-31 provides a direct replacement path without changing the original valve train layout.

Melling recommends replacing push rods as a set during service to maintain consistent valve train geometry and performance. This part cross-references Continental 48014 for the same application.

What It Helps Address

• Bent or worn push rod replacement
• Incorrect valve train geometry from aged components
• Noise caused by inconsistent valve train motion
• Loss of proper valve lift transfer
• Service needs on stock engine rebuilds and maintenance

Installation Notes and Tips

Verify push rod length, tip style, and diameter against the engine specification before installation. Check for straightness and inspect related valve train components for wear before reassembly. Use the MPR-31 only where the listed dimensions and stock application match the engine requirements.
