Dorman 03411B Exhaust Manifold Hardware Kit

Exhaust Manifold Hardware for Ford Applications

Dorman 03411B is an exhaust manifold hardware kit built to match the original hardware used to secure the exhaust manifold to the engine on specified vehicles. Made from metal with a standard replacement grade, it is a direct-fit hardware solution for Ford, Lincoln, and Mercury applications that need OE-style exhaust manifold fasteners.

For Ford F-150, Ford Expedition, Ford Explorer, and related V8 applications, this hardware supports a proper manifold-to-engine connection when the original fasteners are worn, damaged, or missing. The Dorman 03411B part number is also a practical match for service work on high-heat exhaust repairs where correct thread size and fitment matter.

Key Features

• Standard replacement exhaust manifold hardware kit
• Metal construction for reliable service in exhaust applications
• Matches original hardware requirements for specified vehicles
• Thread size: M8-1.25 on both ends
• Designed for Ford, Lincoln, and Mercury fitments across multiple model years
• Cross-reference: this part cross-references N811313S431 for the same application

Detailed Description

Dorman 03411B exhaust manifold hardware is engineered to restore the fastener interface between the exhaust manifold and engine on a wide range of Ford trucks, vans, SUVs, and performance vehicles. The hardware is made from quality metal and follows the original thread specification, helping ensure proper alignment during exhaust manifold service. This part number is a strong fit for long-tail searches such as exhaust manifold hardware kit for 1997-2014 Ford F-150, exhaust manifold studs and nuts for Ford Expedition, and replacement manifold hardware for Lincoln Navigator and Mercury Mountaineer applications.

Compatible With 1997-2014 Ford F-150, N/A; 1997-2014 Ford Expedition, N/A; and 1998-2014 Lincoln Navigator, N/A, among many other listed Ford, Lincoln, and Mercury models. The Dorman 03411B is also relevant for Ford E-Series vans, Explorer, Ranger, Crown Victoria, Mustang, and Super Duty applications where OE-style exhaust manifold fasteners are required.

Common Repair Uses

• Replacing corroded or heat-damaged exhaust manifold fasteners
• Restoring a secure manifold-to-engine connection after exhaust service
• Addressing exhaust leaks caused by loose or missing hardware
• Repairing stripped or worn manifold stud threads
• Supporting reassembly after manifold removal on V8 Ford applications

Installation Notes and Tips

Verify thread size M8-1.25 before installation and compare the original hardware to the replacement kit. Clean the mounting surfaces and threaded holes before assembly to help achieve proper clamping force. Because exhaust manifold hardware is exposed to high heat cycles, follow the vehicle service procedure and torque specifications for the specific engine and model.

Quality Assurance

Dorman manufactures this exhaust manifold hardware kit as a standard replacement part for specified OE applications. It is built to match the original hardware requirements for secure exhaust manifold attachment on listed vehicles.
