Dorman Exhaust Manifold Hardware and Gasket Kit 57175 — Direct-Fit Replacement, Corrosion-Resistant Fasteners

The Dorman 57175 kit provides direct-fit replacement gaskets and mounting hardware to restore a tight, reliable seal between the exhaust manifold and cylinder head.

If the exhaust manifold gasket or its attaching hardware has deteriorated, swapped parts or an ongoing leak can cause noise, reduced efficiency and exhaust escape. The Dorman 57175 Exhaust Manifold Hardware and Gasket Kit contains the matched components engineered to match original fit and restore the connection as technicians service the manifold or replace worn pieces.

How does this kit restore exhaust sealing and reduce noise?

The kit replaces both the sealing gasket and the fasteners that hold the manifold to the cylinder head, eliminating gaps caused by warped or broken parts. Properly matched components re-establish pressure containment and reduce exhaust leaks that generate ticking or rumbling sounds.

• Includes gaskets sized to the original mounting pattern for consistent sealing
• Hardware replaces fatigued bolts and studs that can loosen or snap
• Prepares the mating surfaces for uniform clamping to stop exhaust bypass

What components come in the Dorman 57175 kit and how are they built?

This kit bundles the gasket(s) and the necessary mounting hardware chosen to mirror the factory pieces for the listed vehicles. Materials and manufacturing follow defined specifications so parts meet expected durability and installation tolerances.

• Exact-fit gasket(s) crafted to original mounting geometry
• Replacement bolts, studs, nuts or washers selected for strength and fit
• Corrosion-resistant finishes and controlled tolerances for reliable clamping

Will the Dorman 57175 kit fit my vehicle and how do I confirm fitment?

Fitment varies by make, model and engine trim; Dorman supplies this kit for specific vehicle applications. Before purchasing, use the vehicle lookup or garage tool and enter your year, make, model and engine to verify exact compatibility.

• Check the online fitment tool with your vehicle details for confirmation
• Compare included part shapes and bolt patterns to the original pieces
• Contact seller or Dorman support if unsure about specific engine variants

How should the kit be used during exhaust manifold service?

Replace the gasket and any damaged or corroded fasteners whenever the manifold is removed or leaks are present. Follow torque specifications from the vehicle manufacturer and inspect mating surfaces for warping before installation.

• Clean mating surfaces of carbon and old gasket material before install
• Use manufacturer torque sequence and values to avoid warping
• Replace any additional worn exhaust components that interfere with sealing

Who this kit is for: The Dorman 57175 Exhaust Manifold Hardware and Gasket Kit is intended for DIY mechanics, independent shops and fleet technicians working on the specific vehicle applications covered by this part number. It’s suited for anyone replacing a leaking manifold gasket, refreshing fatigued mounting hardware during repairs, or restoring a secure exhaust connection after manifold service. Verify fitment before ordering and follow vehicle torque and service procedures for best results.
