Description
Replace the grid heater or intake manifold gasket on your 1989–2007 Dodge Ram 5.9L Cummins with this genuine Cummins replacement gasket.
This semi-metallic gasket is designed to provide the proper sealing surface while also maintaining the correct electrical grounding required by the factory grid heater system.
Whether you're servicing the factory grid heater, replacing an intake component, or simply need a fresh gasket during reassembly, using the correct gasket helps ensure a proper seal and reliable grid heater operation.
Features
- Fits 1989–2007 Dodge Ram 5.9L Cummins
- Genuine Cummins replacement gasket
- Semi-metallic construction
- Provides proper grid heater grounding
- Provides a reliable seal between intake components
- Ideal for grid heater and intake manifold service
- Cummins Part Number: 3969988
Why the Correct Gasket Matters
On grid-heater-equipped applications, this gasket does more than simply seal the intake connection.
The semi-metallic construction helps maintain the electrical grounding required for proper grid heater operation, making gasket selection important whenever the intake or grid heater is removed.
Applications
Designed for:
- 1989–1993 Dodge Ram 5.9L Cummins 12-Valve
- 1994–1998 Dodge Ram 5.9L Cummins 12-Valve
- 1998.5–2002 Dodge Ram 5.9L Cummins 24-Valve
- 2003–2007 Dodge Ram 5.9L Cummins 24-Valve
Important Notes
- Cummins Part Number: 3969988
- Fits 1989–2007 5.9L Cummins applications
- 1989–1998 12-Valve applications require 1 gasket to refit the intake air horn
- 1998.5–2007 24-Valve applications require 2 gaskets to refit the intake air horn
- Semi-metallic gasket
- Designed for proper sealing and grid heater grounding
- Recommended whenever the existing gasket is damaged or disturbed during service
- Verify application and required quantity before ordering
Glacier Tech Tip
If your truck retains a functional grid heater, don't treat this as just another intake gasket.
The semi-metallic design helps provide the grounding path for the grid heater, so using the proper gasket is important for both sealing and correct grid heater operation.
Also remember the required quantity changes depending on the engine:
1989–1998 12-Valve = 1 gasket
1998.5–2007 24-Valve = 2 gaskets
