Without knowing what axle capacity you have it's hard to say exactly what leaf spring you would need. But for a 5 leaf spring we only have 6k axle springs like the part # e34SR which is 25-1/4 inches long overall. Normally the two pieces of info needed for replacement springs is axle capacity (most important) and length so that you hopefully don't have to move hangers. The amount of leafs does not typically matter.

The hangers you currently have on your trailer are ones I have run into before. That being said, I spoke with MORryde and the #MR27ZR will still fit your trailer, but there is a modification that will need to be made. You’ll have to trim according to…
