FAQ

Is this seal compatible with other truck models?

The seal is specifically engineered for 2011‑2018 Ram 3500 and 2003‑2010 Dodge Ram 3500. Compatibility with other models is not guaranteed.

Can I install the seal myself?

Yes, the seal is designed for straightforward installation with standard tools. Follow the included instructions and ensure the bearing housing is clean before fitting.

What does “EP lubricant resistant” mean?

EP (Extreme Pressure) lubricants contain additives that can cause swelling in some seal materials. This seal’s formulation resists that swelling, maintaining its shape and sealing capability.

How does the spring‑loaded feature benefit performance?

The spring mechanism maintains constant contact with the bearing surface, compensating for wear and thermal expansion, which helps prevent leaks.

What is the warranty on this product?

National offers a limited one‑year warranty covering manufacturing defects. Contact customer service with your purchase details for assistance.
