Buying Guide

Confirm bolt pattern and lug count

Match the hub's bolt pattern (for example 5x4.5) and lug count to your trailer wheel to ensure proper fit and safe mounting

Verify spindle number and fit

Use the spindle number (such as #84 for 3500 lb axles) or measure spindle diameter and taper to pick a hub kit that fits your axle

Check weight rating vs trailer load

Choose hubs rated for your trailer's gross axle weight—kits specifying 3500 lb or higher are common for small utility trailers

Inspect included bearing and seal sizes

Confirm the hub kit includes the correct inner/outer bearings, seals, nuts and dust caps so you won't need extra parts or machining

Prefer kits with corrosion-resistant components

Look for hubs and caps with plated or stamped finishes to reduce rust risk in road and marine environments
