Cummins 1998.5–2024 Dodge Ram 5.9L / 6.7L Cummins Exhaust Manifold Stud (3944655)
Description
Replacing an exhaust manifold, repairing an exhaust leak, or refreshing old exhaust hardware on your 1998.5–2024 Dodge Ram 5.9L or Ram 6.7L Cummins?
The Cummins 3944655 Exhaust Manifold Stud is a genuine factory Cummins replacement stud designed for securing the exhaust manifold to the cylinder head. It is designed for use with the Cummins 3902662 Exhaust Manifold Nut and is sold individually.
Exhaust manifold hardware is subjected to extreme heat, repeated thermal cycling, corrosion, and years of engine operation. During manifold removal, it's common to find studs that are heavily corroded, damaged, or simply not worth reinstalling.
If you're already replacing or servicing the exhaust manifold, fresh factory hardware is cheap insurance against having to tear everything apart again because of questionable old fasteners.
Features
- Genuine Cummins replacement component
- Cummins Part Number: 3944655
- Fits 1998.5–2024 Dodge Ram / Ram 5.9L & 6.7L Cummins
- Factory exhaust manifold mounting stud
- Designed for use with Cummins 3902662 Exhaust Manifold Nut
- Direct replacement for factory hardware
- Ideal for exhaust manifold replacement or service
- Great replacement for damaged, corroded, or missing studs
- Sold individually
Why Replace Exhaust Manifold Hardware?
The exhaust manifold is exposed to some of the highest temperatures anywhere on the engine.
Every time the engine heats up and cools down, the manifold and its mounting hardware go through another thermal cycle. Add corrosion, age, previous repairs, and years of service, and the original studs can become difficult to remove or questionable to reuse.
If an exhaust manifold stud has:
- Damaged threads
- Heavy corrosion
- Damage from removal
- Excessive wear
- Broken or compromised threads
replacing it with the correct Cummins 3944655 Exhaust Manifold Stud is the better choice while the manifold is already removed.
Factory Stud & Nut Combination
The Cummins 3944655 Exhaust Manifold Stud is designed for use with the Cummins 3902662 Exhaust Manifold Nut.
If you're refreshing exhaust manifold hardware, we recommend inspecting both components rather than replacing one while reinstalling heavily worn or corroded hardware on the other side.
Both the stud and nut are sold individually, allowing you to replace only what you need or build a complete fresh set for an exhaust manifold installation.
