Buying Guide
What size is your trailer axle? Most common boat and utility trailers use 1-1/16″, 1-3/8″, or 1″ hubs. Choose a kit that explicitly matches your axle diameter and spindle type (often #84 spindles for 1-3/8″ axles).
Do you need inner and outer bearings together? Many kits include both inner and outer bearings, plus races and seals. If your hub requires separate parts, look for a kit that includes both bearing sets and the appropriate seals.
Are extra parts important? Some bundles add dust caps, cotter pins, washers, and spindle nuts. If you want fewer trips to the store, choose a kit that includes these extras.
Material quality matters. Chrome steel bearings provide durability and quiet operation when properly lubricated. Verify that seals match your hub for a reliable, leak-free seal.
Packaging and protection. Well-packaged kits reduce the chance of damaged parts during shipping. Check for sturdy boxes and bubble wrap if you are ordering online.
