National Wheel Seal for Ram 3500 (2011–2018) — 710563 spring-loaded multi-lip

National 710563 is a spring-loaded, multi-lip wheel seal engineered to stop leaks and protect bearings on 2011–2018 Ram 3500 and compatible 2003–2010 Dodge Ram 3500 axles.

National has supplied sealing components for decades, and the 710563 continues that legacy with a design focused on reliability and long service life. This wheel seal uses multiple sealing lips and a spring to maintain consistent contact at the hub, resisting common axle fluids and operating across a wide temperature band so it performs under everyday driving and heavier-duty conditions.

How does this seal prevent axle leaks?

The multi-lip profile creates several barriers against fluid migration while the internal garter spring keeps constant radial pressure on the sealing surface. Together these features reduce seepage past the hub and minimize contamination of bearing surfaces.

• Multi-lip geometry for staged sealing
• Spring-loaded tension maintains contact over time
• Formulated to resist swelling in hydrocarbon-based fluids

Will the National 710563 fit my truck?

This part is designed for Ram 3500 trucks from 2011 through 2018 and also fits Dodge Ram 3500 models from 2003 to 2010. Always verify fitment against your vehicle’s year, make, model, engine, and trim before ordering to ensure correct application.

• Primary fit: 2011–2018 Ram 3500
• Additional fit: 2003–2010 Dodge Ram 3500
• Confirm fit using vehicle-specific details and seller fitment notes

What materials and operating conditions does the seal handle?

The seal compound and design resist degradation from extreme temperatures and common axle lubricants, including extreme-pressure (EP) formulations. National rates the part for a broad service range to handle typical driving environments and heavier loads.

• Temperature capability: approximately -20°F to 300°F (-29°C to 149°C)
• Designed for compatibility with EP lubricants
• Low swell behavior in hydrocarbon fluids preserves sealing performance

What should I know before installation?

Proper installation and verifying fitment notes are essential for dependable performance. Inspect the hub and bearings for wear, use the correct installation tool or driver to avoid distorting the seal, and double-check the seller's fitment details if an "i" note appears in the fitment tool.

• Check hub and bearing surfaces for damage before installing
• Use a seal driver to seat the part evenly without deforming the lips
• Review fitment notes and vehicle specifics on the product listing

Who is this for? Technicians, DIY truck owners, and fleet managers replacing wheel seals on Ram 3500 or Dodge Ram 3500 axles will appreciate the National 710563 for its proven sealing design and compatibility with heavy-duty lubricants. It’s appropriate for routine axle servicing, bearing overhauls, and any repair where a durable, spring-loaded multi-lip seal is required.
