Dorman 674-895XD Exhaust Manifold

Dorman 674-895XD Exhaust Manifold for Ram

Dorman 674-895XD is a standard replacement exhaust manifold for select Ram heavy-duty trucks. It is built from cast iron and finished with a specialized ceramic coating that helps distribute heat more evenly, supporting reduced thermal stress and smoother exhaust gas flow.

• Cast iron construction for exhaust durability
• Ceramic-coated surface to manage heat more evenly
• Round port shape with 1.5 collector port diameter
• 12 mounting holes for application-specific fitment
• Heat shield included
• Gasket or seal included
• Mounting hardware included
• No oxygen sensor port
• Metallic gray finish

Fitment Details

Compatible with 2011-2019 Ram 2500, w/Ceramic Coating; 2011-2018 Ram 3500, w/Ceramic Coating; 2007-2010 Dodge Ram 2500, w/Ceramic Coating; and 2007-2010 Dodge Ram 3500, w/Ceramic Coating. This Dorman exhaust manifold is a direct-fit option for Ram 2500 and Ram 3500 applications that require the ceramic-coated configuration.

This part cross-references 68027070AA for the same application.

What It Helps Address

• Cracked or warped exhaust manifold surfaces
• Exhaust leaks at the manifold-to-cylinder-head interface
• Heat-related stress in high-load Ram 2500 and Ram 3500 service
• Restricted exhaust flow caused by damaged manifold passages
• Noise from a failing manifold or sealing surface

Installation Notes

Verify engine-side fitment and the ceramic-coated configuration before installation. Use the included gasket and hardware as specified for the application, and inspect the cylinder head sealing surface, studs, and fasteners for wear or damage before assembly. Because this manifold does not include an oxygen sensor port, confirm sensor routing and exhaust system layout on the vehicle before beginning the job.

Quality Assurance

Dorman manufactures this exhaust manifold as a standard replacement part with cast iron construction and a ceramic coating engineered to manage heat more evenly than an uncoated manifold. For Ram 2500 and Ram 3500 owners, Dorman 674-895XD provides a service-ready replacement for the listed model years and configuration.
