From what I can see your Keystone trailer has a pair of 3,500 lb axles so to upgrade to 5,200 lb axles you'd need the axles, U-bolts, and hubs. In order to choose the correct replacement axle for your trailer you will need to know the dimensions of your current axle's hub face to hub face and spring center to spring center; I have added a link below to a video which walks you through how to measure.

For example, the 5,200 lb Trailer Axle w/ Electric Brakes # e55SR measures 95 inches from hub face to hub face and 80 inches from spring center to spring center. For mounting it you would need the U-Bolt Kit for Mounting 5,200-lb to 7,000-lb, Round Trailer Axles # APUBR-8.

I have added a link below to our entire selection of 5,200 lb axles for you to take a look at.
