Detailed Description

This Dorman exhaust flange stud and nut, part number 03103, is engineered as a direct-fit replacement for original exhaust manifold hardware on a wide range of Chrysler, Dodge, and Plymouth vehicles. It is listed for front-position exhaust manifold service on models such as Dodge D150, Dodge Ramcharger, Plymouth PB250, and Chrysler Imperial, with fitment spanning 1978-1983 model years. The hardware is designed to restore a proper threaded connection at the exhaust flange where heat and vibration can weaken original fasteners over time.

The part number 03103 is also a useful reference when comparing exhaust flange hardware for older Dodge truck and Chrysler passenger car applications.

What It Helps Fix

Broken or stretched exhaust manifold studs
Loose exhaust flange connections
Exhaust leaks at the manifold joint
Corroded or heat-damaged original fasteners
Service issues during exhaust manifold repair or replacement

Installation Notes and Tips

Verify thread size, stud length, and vehicle-specific fitment before installation. Clean the mating surfaces and threaded holes before installing the new hardware to help achieve proper clamping force. Because this part is used in exhaust service, inspect the flange, manifold, and adjoining fasteners for heat damage or corrosion before reassembly.

Quality Assurance

Dorman manufactures this hardware as a standard replacement part designed to match original fit and function on specified applications. The metal construction and Grade 8 bolt specification support reliable fastening in exhaust manifold service.
