Hey Korey, so we need two piece of info to pick out replacement leaf springs for a trailer. We need to know the axle capacity as well as the length of the current springs. I was able to determine that your 2014 Nash 23B has a 3,500 lb axle so that's a start but I don't know the length of the springs.
The most common length of spring would be like the part # e54SR which is 25-1/4 inches which you would need to measure this without a load on the trailer suspension. view full answer...
