We don't carry the MR4 leaf springs but based on my research they look like they are 26 inch double-eye springs like part # e94SR.

For springs of this length and the Tandem-Axle Trailer Hanger Kit for Double-Eye Springs # APT4 the hangers are going to be spaced 30-1/4 inches apart. I have added a link to a video review of the hanger kit as well as a couple help articles on trailer suspension which I recommend checking out.

There are a few differences between slipper springs and double-eye leaf springs. Slipper springs normally have a higher weight capacity, and fewer moving parts, but they tend to ride a little rougher than double-eye. You will need to know the length…
