In order to determine the correct axle for your trailer you will need to take a few measurements. The first measurement will be the overall length of your axle from the face of each hub. The other measnuent you will need to determine is the distance from the center of each spring hole. These two measurements will then be used to ensure you have selected the proper replacement axle.

We have two different axle lengths with a 2,000 weight capacity. The part # T20BTR-6048 measures 60" from hub face to hub face and 48" from spring center to spring center. The part # T20BTR-7258 measures 72" from hub face to hub face and 58" from spring center to spring center. If you have a different hub face and spring center measurement then please let me know what those distances are and I would be glad to see if we have a better option for you.
