Expert Reply:

The only double-eye spring we offer that's near the dimension you mentioned is part # e84SR for a 2000 lb axle. The spring has three leaves, but keep in mind that the number of leaves a spring has doesn't necessarily denote its weight capacity. The # e84SR spring measures 20-3/8, eye to eye. Since trailer springs can flatten out and elongate over time, it's entirely possible that these springs would be the correct replacements.

To get the proper eye to eye dimension of your existing spring, you should measure the spring length with the trailer jacked up with no weight on the suspension.

I'll link you to our FAQ article about trailer suspensions.
