BCBC MPR-667 Engine Push Rod - Intake

Overview

Melling MPR-667 is a standard replacement engine push rod built for intake valve train service in a wide range of Chrysler, Dodge, Jeep, and Ram applications. It uses welded steel construction, ball ends, and a drilled design to support proper valve train geometry and consistent operation.

This push rod is made in the USA and is specified at 6.792 inches in length with a 0.312-inch diameter. It is a direct-fit intake push rod for applications such as Dodge Durango, Ram 1500, and Jeep Grand Cherokee, and it cross-references Monroe Shocks & Struts (e.g., 5045 515AA, 5302 1556BB) for the same application.

Key Features

• Welded steel construction for standard replacement engine service
• Ball-end top and bottom tips for proper valve train contact
• Drilled design for OE-style push rod application requirements
• 6.792-inch length and 0.312-inch diameter
• Made in the USA

Detailed Description

MPR-667 is engineered as a standard replacement push rod for intake-side valve train use. Melling recommends replacing push rods during service to maintain correct valve train geometry and performance, and this part follows that guidance with a welded steel body, ball ends, and drilled construction. The MPR-667 part number is used across many late-model Hemi-based applications, including Chrysler 300, Dodge Charger, Dodge Challenger, Jeep Grand Cherokee, and Ram 1500 platforms.

The Melling Stock line focuses on OE-style replacement parts for everyday engine repair, and this push rod reflects that approach with a precise 6.792-inch length and 0.312-inch diameter. If you are servicing a Dodge Durango, Ram 2500, or Jeep Wrangler intake valve train, MPR-667 provides the specified geometry needed for proper assembly.

What It Helps Address

• Incorrect valve train geometry after push rod wear or damage
• Noise or irregular operation caused by a bent or worn push rod
• Loss of proper valve actuation in intake-side service
• Fitment issues when the original push rod no longer matches the required length

Installation Notes

Verify the required intake application, length, and diameter before installation. Match the ball-end configuration and drilled design to the original specification for the engine being serviced. Replace push rods as a set only when the service procedure or inspection results call for it, and confirm valvetrain components are within specification before final assembly.

Quality Assurance

Melling builds this push rod to stringent manufacturing specifications using quality materials and processes. The MPR-667 is part of the Stock line and is made in the USA for standard replacement engine applications.
