I have a way that you can determine what axle you need. Unfortunately, from your trailer model, I could not find the length specs of your 7k axles.

Since you have a 7k axle, the next thing you need to know is the measurement from the left hub face to the right hub face as well as the left spring center to the right spring center. For example, if you have a hub face measurement of 94 inches and a spring center measurement of 79 inches, I recommend the Trailer Axle Beam with Easy Grease Spindles - 94" Long - 7,000 lbs # e93GR. As another example, if you have a hub face measurement of 95 inches and a spring center measurement of 79-1/4 inches, that is the Dexter Trailer Axle Beam with 4" Drop E-Z Lube Spindles - 95" Long - 7,000 lbs # 8327860.

I went ahead and attached a diagram of the hub face/spring center measurement of the # 8327860 to provide you with how to make those measurements to determine what length you need.
