Dorman 57175 Exhaust Manifold Gasket and Hardware Kit - Left or Right

Dorman 57175 Exhaust Manifold Gasket Kit

Dorman 57175 is an exhaust manifold gasket and hardware kit built to restore the seal between the cylinder head and exhaust manifold on specified vehicles. It is a direct-fit OE-style replacement for applications such as Chevrolet Silverado 2500 HD, GMC Sierra 2500 HD, and Cadillac Escalade, with fitment covering both left and right bank applications depending on the vehicle.

Key Features

• OE-style fit and function for the exhaust manifold-to-cylinder head connection
• Exhaust manifold gasket material includes composite graphite and steel construction
• Exhaust flange sealing uses a steel O-ring design
• Exhaust manifold hardware grade 10.9 with M8x1.25 thread specification
• Exhaust flange hardware grade 10.9 with M10x1.5 thread specification
• Compatible with a wide range of GM trucks, vans, SUVs, and performance models
• Part number 57175 for easy catalog matching

Detailed Description

This Dorman exhaust manifold gasket and hardware kit is engineered to match the original component fit and function so the exhaust connection stays secure at the cylinder head. The design supports proper sealing at the manifold and flange areas, helping maintain exhaust integrity on vehicles such as Chevrolet Express, Silverado, Tahoe, GMC Savana, Sierra, Yukon, and Cadillac Escalade applications. Part number 57175 is also a useful cross-reference for service work where OE-style replacement is required.

This part cross-references Monroe Shocks & Struts (e.g., MSB92467) for the same application.

What It Is Used For

• Exhaust leaks at the manifold-to-cylinder head sealing surface
• Broken, stretched, or corroded exhaust manifold fasteners
• Flange sealing issues at the exhaust connection
• Noise from a leaking exhaust manifold area
• Service replacement on GM trucks, vans, SUVs, and performance cars

Installation Notes and Tips

Verify bank position before ordering, since this kit is listed for both left and right side applications across different vehicles. Confirm thread sizes and hardware length during service: exhaust manifold hardware uses M8x1.25 threads, while exhaust flange hardware uses M10x1.5 threads. Clean the mating surfaces thoroughly before installation and inspect the manifold and cylinder head for warpage or damage that could affect sealing.

Quality Assurance

Dorman designs this kit to match original fit and function for a secure exhaust connection on specified vehicles. The components are built to OE-style specifications for service replacement on the listed applications.
