The closest option we have to the measurements you took on your existing leaf springs is the 3-Leaf Double-Eye Spring # e59SR. This 3-leaf stack measures 23-1/8 inches from the center of one eye to the center of the other and is designed for a 3,500 pound axle.

Older leaf springs will stretch over time so it's not abnormal that the new leaf spring will be shorter than the measurement you took but I do still recommend verifying the length on your current springs. Make sure you have the trailer jacked up so that there isn't any weight on them when measuring.

A 3,500 pound axle typically features a 2-3/8 inch diameter for which the U-Bolt Kit # APUBR-1 will work great. If your axle does in fact have a 3 inch diameter though then you will want to use the U-Bolt Kit # APUBR-8 instead. A 3 inch diameter axle will usually have a higher weight capacity of 5,200 or 7,000 pounds so it might be a good idea to also verify both the diameter and capacity of your trailer's axle.

We do recommend replacing leaf springs in pairs so that you are using the same set with the same amount of wear on each side of the trailer.
