Cummins 1998.5–2018 Dodge Ram 5.9L / 6.7L Cummins Exhaust Manifold Spacer (3945252)
Description
The Cummins 3945252 Exhaust Manifold Spacer is a genuine Cummins replacement spacer used with the exhaust manifold mounting hardware on 1998.5–2018 Dodge/Ram 5.9L and 6.7L Cummins trucks.
These spacers play an important role in allowing the exhaust manifold to properly expand and contract through repeated heat cycles. Using the correct spacers helps reduce stress on the manifold while preventing excessive gasket compression that can contribute to exhaust leaks or manifold damage.
If you're replacing an exhaust manifold or refreshing the factory mounting hardware, don't overlook the spacers.
Features
- Fits 1998.5–2018 Dodge/Ram 5.9L & 6.7L Cummins
- Genuine Cummins replacement spacer
- Allows proper exhaust manifold expansion and contraction
- Helps reduce stress that can contribute to manifold cracking
- Helps prevent excessive exhaust manifold gasket compression
- Direct replacement for the factory spacer
- Cummins Part Number: 3945252
Applications
Designed for:
- 1998.5–2002 Dodge Ram 2500 & 3500 5.9L Cummins
- 2003–2007 Dodge Ram 2500 & 3500 5.9L Cummins
- 2007.5–2009 Dodge Ram 2500 & 3500 6.7L Cummins
- 2010–2012 Ram 2500 & 3500 6.7L Cummins
- 2013–2018 Ram 2500 & 3500 6.7L Cummins
Important Notes
- Cummins Part Number: 3945252
- Sold individually
- 12 spacers are required for a complete exhaust manifold installation
- Designed for use with the proper Cummins exhaust manifold mounting hardware
- Inspect the bolts, studs, lockplates, gaskets, and spacers during exhaust manifold service
- Verify vehicle application before ordering
Glacier Tech Tip
These spacers aren't just oversized washers.
The exhaust manifold experiences significant expansion and contraction as exhaust temperatures change. The factory spacer design helps accommodate that movement while maintaining the proper clamping force on the manifold and gaskets.
When replacing an exhaust manifold, it's a good idea to inspect the entire mounting hardware system rather than simply reusing worn or damaged components.
