Buying Guide

Match bearing size to your spindle

Confirm whether your trailer uses 30205/25mm bearings or an #84 spindle before buying to ensure proper fit and safe operation

Check kit completeness

Look for kits that include matched inner and outer bearings, races, seals and grease caps when replacing a full hub assembly to avoid extra parts orders

Verify load rating vs. axle capacity

Choose a kit specified for your axle’s capacity (examples in this list cover 2000–3500 lb spindle classes) so bearings aren’t undersized for trailer weight

Prefer sealed parts for marine use

For boat trailers, select kits with robust seals to resist water intrusion and corrosion on #84 spindle applications

Check user rating and seller details

Use average user ratings and product Q&A to confirm long-term durability and that components (e.g., hub fit, race quality) match your trailer model
