Thank you for providing that helpful information. Based on your measurement and the 3,750 lb axle rating I recommend the 4-Leaf Double-Eye Spring for 4,000-lb Trailer Axles - 26" Long # e22YR. These leaf springs are slightly shorter but that won't be an issue. Leaf springs will become longer as they wear out, so a replacement will be shorter than your current measurement.

It is worth noting that leaf count doesn't matter. This is a 4-leaf spring but the important factor is the weight capacity. A single leaf, 3- leaf, 4-leaf, etc. could all have the same spring capacity. Also, even though you will have leaf springs with a combined 4,000 lb capacity you will still be limited by your axle or the weakest component of your trailer.
