Buying Guide

Match bolt pattern and lug count

Confirm your trailer's bolt pattern (for example 5-bolt/5-lug 4.5") to ensure hubs mate correctly with wheels and studs

Verify spindle type and capacity

Select a hub kit specified for your spindle (straight, tapered, or a numbered spindle like #84) and trailer rating (e.g., 2,000–3,500 lb) to ensure load compatibility

Choose correct bearings and seals

Kits that include bearings and seals (for example bearing kits for 1-3/8" to 1-1/16" tapered axles) simplify installation and maintain hub longevity

Consider brake drum compatibility

If you have electric brakes, pick a hub/drum assembly sized to your system (common sizes include 10" x 2-1/4") to avoid retrofit mismatches

Check user ratings and value score

Compare average user ratings and value scores across similar-spec hubs to gauge reliability for the price tier under $100
