Dexter 8,000 lb 865 Hub Bearings, E-Z Lube & Oil-Cap Parts Guide
Dexter 8,000 lb 865-series trailer hubs use a 25580 inner bearing cone and a 02475 outer bearing cone, with matching 25520 and 02420 cups. The grease-lubricated E-Z Lube and oil-lubricated hub versions do not use the same cap and seal arrangement. Use the component guide below to find the correct replacement parts for your hub.

Grease and E-Z Lube component numbers
Reference numbers follow the manufacturer's hub illustration. Items with a specific grease-cap or spindle design apply only to that arrangement.
