Detailed Description

The Melling MPR-342 push rod is engineered for stock engine builds that require accurate valve train geometry and consistent operation. Its welded steel body, 0.312-inch diameter, and ball-end tips match common OE-style push rod requirements, while the drilled construction supports proper oil flow through the valve train. This part number is used across many Chevrolet, Pontiac, Buick, Oldsmobile, GMC, Isuzu, Cadillac, and Jeep applications, including Chevrolet Camaro, Chevrolet S10, and Pontiac Firebird fitments. MPR-342 is a direct replacement choice for standard engine service where maintaining original geometry matters. Melling recommends replacing push rods during service to help preserve valve train performance, and MPR-342 is one of the brand’s stock-line options for OEM-style applications. 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 valve train geometry after engine service
• Addressing noisy or inconsistent valve train operation
• Supporting proper lifter-to-rocker arm motion
• Maintaining OE-style engine operation in compatible applications

Installation Notes and Tips

Verify push rod length, diameter, and tip style before installation. Confirm the application against the vehicle’s engine configuration, since fitment includes both N/A and Intake positions in the listed vehicles. Inspect related valve train components for wear before reassembly, and replace any damaged parts to avoid repeat service.

Quality Assurance

Melling manufactures this push rod to stringent specifications using quality materials and processes. The brand’s OE and performance engine component experience supports consistent fit and function in stock replacement service.
