Question:
Will spring work on a 5200 lb axle

Hi Loren!
There is no reason the 4-Leaf Double-Eye Spring for 6,000-lb Trailer Axles - 25-1/8" Long # EM58AJ wouldn't fit a 5,200 pound axle. It would technically be a little overrated for it, but that's a pretty common thing people do. Just make sure this matches your current spring as closely as possible.
Also make sure your U-Bolts are long enough. They probably are, but just make sure. This spring has four leaves that measure 1/4" each. If your U-Bolts are not long enough, or are looking a little worse for wear, you could also grab the U-Bolt Kit for Mounting 5,200-lb to 7,000-lb, Round Trailer Axles - 7" Long U-Bolts # APUBR-8.

Hi Loren, Did you find that the 4-Leaf Double-Eye Spring worked well for your 5,200 lb axle? I'm curious to know if it fit your trailer and if you needed to replace the U-Bolts as well. Your experience could really help others in a similar situation!
