BCBC MPR-56 Engine Push Rod

Engine Push Rod for Stock Applications

This Melling engine push rod is a standard replacement part for classic Chrysler, Dodge, Plymouth, and DeSoto valve train applications. Part number MPR-56 is built for stock engine setups where correct valve train geometry matters.

• Welded steel construction for consistent strength and rigidity
• Rounded ends at both tips for proper contact at the valve train interfaces
• Standard replacement grade for OEM-style service work
• Made in the USA

MPR-56 is specified for a wide range of vintage Chrysler, Dodge, Plymouth, and DeSoto engines, including applications such as the Chrysler Newport, Dodge Coronet, and Plymouth Fury. The 0.312-inch diameter and 8.635-inch length match the listed stock applications, while the non-drilled design keeps the part focused on original-style engine service. Melling also notes that new push rods should be installed to maintain proper valve train geometry and performance. This part cross-references Monroe Shocks & Struts (e.g., 74-6056, 48032) for the same application.

Used For

• Replacing worn or bent push rods in stock valve train service
• Restoring correct valve train geometry after engine wear
• Addressing noisy or inconsistent valvetrain operation caused by damaged push rods
• Supporting proper lifter-to-rocker arm motion in original-style engines

Installation Notes and Tips

Verify push rod length, diameter, and tip style against the engine specification before installation. Confirm fitment by year, make, model, and serial-number notes where listed, especially on 1967 Dodge truck applications. Use this part only where the stock application and dimensions match the engine build.

Quality Assurance

Melling manufactures this push rod to stringent specifications using quality materials and controlled production processes. The part is made in the USA and is intended for standard replacement service in compatible valve train applications.
