Will Changing Travel Trailer Axle Increase the Trailers Overall Weight Capacity


I have a brand new 2015 travel trailer with low GVWR due to the axles used. They are 2800 pound Dexter Axles, part number 4330537. I cant seem to find any information on this part number, but would like to upgrade to a pair of 3500 pound axles if possible?

We do offer axle beams alone and also complete axle kits that include hub/drums, brakes etc. All can be viewed by clicking on the included link. I also was unable to find a cross-reference for your axle number 4330537. This may be a production code rather than a part number.

You can certainly change out your axle to a higher-rated part, such as the 3500-lb-rated Dexter part # T3584F-EZ-8974, but this will NOT necessarily increase your trailer's capacity. The trailer's frame design and its other features also bear on its ultimate weight capacity. You also want to be sure your hub face to hub face, and your spring center to spring center measurements for a new axle match your current dimensions.

I do recommend you check with your trailer manufacturer by giving them your VIN number to see if the trailer's frame and overall structure will let you get useful additional capacity by changing out the axle. Swapping in a new higher-rated axle will be okay if the axle is the weakest link in the overall trailer design, but this is up to the manufacturer to decide.
