Weight Capacity of Flatbed Trailer with Dual 2-3/8 Inch Diameter Axles

Published 11/14/2018

Question:

I have a flatbed trailer with dual 2 3/8inch axles. What is the capacity of these axles combines? I have a 1100 lLb trailer with a VW Jetta 3300Lbs on the trailer. Coupler is 5000 Lb rated, hitch 7500 Lb rated.

The 2-3/8 inch axles are 3,500 lb axles like # e43SR, so combined you would have a 7,000 lb capacity. The trailer weight will not count in the GVWR of the trailer capacity but the weight will count toward the towing capacity of the hitch, ball mount, hitch ball, and of course the vehicle towing capacity.

The component with the lowest rated capacity will be your max capacity. So your towing capacity will be 5,000 lbs based on the coupler and the trailer weight is currently 4,400 lbs, so you want to make sure you don't add more than 600 lbs to your trailer in other cargo.
