Will this wheel seal fit my truck?

Compatibility is key — this National 710563 fits 2011–2018 Ram 3500 and is also listed for 2003–2010 Dodge Ram 3500 models. Always verify fitment against your truck’s year, make, model, engine and trim before ordering.

• Also fits: 2003–2010 Dodge Ram 3500
• Check vehicle info and any vendor notes or confirmed-fit bars before purchase

How does the National design keep grease and contaminants out?

The seal uses a multi-lip profile backed by a tensioned spring that holds lips snug to the shaft, maintaining contact as components wear. This mechanical arrangement helps reduce leakage while keeping dirt and moisture out of the hub assembly.

• Spring-loaded lip keeps constant radial pressure
• Multi-lip geometry creates multiple sealing surfaces
• Durable elastomer resists swelling and degradation

Can it handle harsh fluids and temperatures?

Materials and construction were chosen for resistance to EP (extreme pressure) lubricants and low swell when exposed to hydrocarbons. The operating temperature window supports common service conditions encountered in light- and heavy-duty trucks.

• Temperature range: roughly -20°F to 300°F (-29°C to 149°C)
• Formulated for reduced swell in hydrocarbon fluids
• Engineered to tolerate EP axle lubricants without rapid degradation

What should I expect during installation and service life?

Installation follows standard wheel-seal replacement procedures and will typically require proper seating and inspection of mating surfaces. When installed correctly and paired with good hub maintenance, the National 710563 provides extended service life comparable with other premium aftermarket seals.

• Requires clean shaft and housing surfaces for best sealing
• Check bearing and hub condition before installing a new seal
• Delivers consistent performance for repair and maintenance jobs

Who is this for: The National 710563 wheel seal is aimed at technicians, fleet managers and DIY truck owners who need a direct-fit replacement for Ram 3500 axle and hub sealing. If you maintain a 2011–2018 Ram 3500 or an earlier 2003–2010 Dodge Ram 3500 and want a quality, spring-loaded multi-lip seal with good chemical resistance and broad temperature capability, this part is a practical option.
