This 3,500lb Capacity Trailer axle is intended to replace your broken or bent axle on your trailer. A 3,500 lb Capacity Trailer Axle Beam is most commonly used on trailers that are running 5 Lug Brake Drums or Idler Hubs. This Axle includes standard 4 Hole Brake Flanges welded to the axle beam for mounting Drum and Disc Brakes. 
You would need a replacement axle if you have noticed tread wear due to improper tire alignment, which is the result of a bent trailer spindle on one side. In addition, another common reason for axle damage results from over loading the trailer, which will result in noticing tread wear on the insides of both trailer tires. If you trailer experiences exposure to corrosive environments, such as a boat trailer, rust damage is another possible culprit for axle replacement. 
This 3,500 lb Capacity Trailer Axle is made with 3/16" Steel Wall Thickness, measures 2 3/8" in diameter, and features #84 Spindles welded into the beam. This listing is for the Beam Only. This Axle is for trailers with a Leaf Spring Suspension. We offer all additionally needed components separately for you to build the exact axle kit that you are needing for your trailer.
