Expert Reply:
From your photo, it looks like you have a Dexter axle, part number 51955. From my research, it appears this is likely a 3,500-lb axle. However, the weight capacity should be listed on the axle itself, so it would be best to confirm this before purchasing a replacement.
You'll also need to know the axle length. I've attached a photo showing where to measure your axle for the correct length. I've also included a link to our axle product listings. Once you know your measurements, you can use the filters on the left side of the page to choose the correct axle. Or, if you'd like, you can send me your axle measurements, and I will be more than happy to make a recommendation for you.
