It sounds like you are looking for a u bolt kit for a 3,500 lbs axle. The 3-Leaf Double-Eye Spring for 4,000-lb Trailer Axles - 25-1/4" Long item # e57SR will work great for a tandem axle suspension system. For your ubolt kit you're going to need the Redline U-Bolt Kit for Mounting 3,500-lb, Round Trailer Axles - 5-1/2" Long U-Bolts item # APUBR-1. I have attached a diagram so you can compare the dimensions. It's better to use a piece of string to measure a round axle than a tape measure. This kit fits an axle diameter of 2-3/8" and a spring width of 1-3/4".
