We offer individual axle components but also axle kits in various weight ratings and some even include hub/drum assemblies and electric brakes. Using a complete kit ensures compatibility of parts and that everything has a full working life ahead of it. A complete kit like the 3500-lb rated # e43SR includes an 89-inch axle, 5-on-4-1/2-inch bolt pattern hub/drums, electric brakes, bearings, seals, etc.

In a 5K rated axle system we do not offer beam-type axles like the Dexter noted above but we do offer Timbren axle-less suspension systems such as # A35RS545E. This Timbren kit mounts to your trailer frame and eliminate the weight and reduced ground clearance of a standard axle. This kit includes the rubber suspensions, spindles, hubs, brakes, bearings, races, seals, etc.

I recommend a complete kit with spindles because otherwise you'll need to have a professional welder install new spindles on your axles. This requires specialized equipment and training since spindles MUST be welded on perfectly straight or problems with tracking and tire wear can result.

I have linked our main page for trailer axles which you can use to see all options. Click on the weight rating, appropriate axle length for your trailer, the spring center dimension and your wheel bolt pattern to see kits you can consider.

For reference I have linked an article on routine trailer maintenance that may be helpful to you. We do recommend packing your bearings every year or every 12K miles.
