Buying Guide

Confirm bolt pattern and lug count

Match the hub's bolt pattern (for example 5×4.5) and lug count to your trailer wheel and spindle to ensure proper fit and safe wheel mounting

Match spindle type and size

Select a hub kit rated for your spindle type—straight, tapered, or specific spindle numbers (e.g., #84)—and axle load capacity to avoid premature wear

Check load rating

Choose hubs and spindles with a gross axle rating that meets or exceeds your trailer’s GVWR; common light-duty options are in the 2,000–3,500 lb range

Decide on brake compatibility

If you need electric brakes, pick a hub/drum assembly sized for your brake system (examples include 10×2-1/4 electric brake drums) rather than a plain hub

Inspect bearing and seal specs

Ensure the kit includes correct bearing sizes and seals for your axle (for example kits for 1-3/8″ to 1-1/16″ tapered axles) to simplify installation and maintenance
