Hi Jeff; to find the right replacement leaf springs you will need to know your axle capacity and find their length. If you don't already know the capacity, check the axle tag to see if it is listed. If you only have a serial number the axle manufacturer will be able to identify it using that number.

I attached a help article below which explains how to measure your leaf springs. The most common measurements are eye to eye or the flat length. Once you have this information you can find the right replacement. For example, if you have a 6k axle and your eye to eye measurement is 26" or the flat length is 28" you can use the # e94SR you were looking at.

Hey Jeff, were you able to get the axle capacity and spring measurements for your Wolf Pack trailer? Once you had those details, did the replacement leaf springs end up being a good fit? Your update could make it easier for the next person working on a similar setup.
