Detailed Description

MPR-105 is a Melling push rod engineered for OEM-style and standard replacement use in classic V8 and inline applications where correct valve train geometry matters. The 0.312-inch diameter, 9.136-inch length, and ball-end configuration make it a direct service part for many stock engines, including applications in Pontiac Firebird, Pontiac GTO, and Chevrolet Impala platforms. Melling recommends replacing push rods during service to maintain proper geometry and performance, and this part number is also referenced as MPR-105 in interchange listings.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Is Used For

• Replacing a worn or bent push rod in a stock valve train
• Restoring correct lifter-to-rocker arm motion
• Addressing valve train noise caused by damaged push rod geometry
• Supporting proper engine operation after top-end service
• Maintaining factory-style valve train dimensions in compatible engines

Installation Notes and Tips

Verify push rod length, diameter, and end style before installation. This part is listed for stock applications and also includes fitments with notes such as except Ram Air engine and without pushrod guide plate, so confirm engine configuration before ordering. Inspect related valve train components for wear, and replace any bent or damaged parts during service.
