I have a few options for you to help with identifying the axle capacity on your trailer. The first and easiest method is simply by crawling under the trailer and looking for the axle tag on the center of the beam. Depending on age, the axle capacity will be printed on the tag. If the capacity is not listed then you can measure the diameter of the beam if round and match this up to the list below. Please note, in order to find the diameter you will need to divide the circumference value by the number pi.

- 1,000-lb - 2,000-lb Axles: 1-1/2" diameter - 1-3/4" diameter - 2-3/8" diameter
- 3,500-lb Axles: 2-3/8" diameter - 3" diameter
- 6,000-lb - 7,200-lb Axles: 3" diameter
- 8,000-lb Axles: 3-1/2" diameter
- 9,000-lb Axles: 4" diameter
- 10,000-lb Or more axles: 5" diameter

Unfortunately, we can't reference serial numbers so if you don't want to go through the steps above or if it's a torsion axle without an axle tag, you'll simply need to reach out to the axle manufacturer.
