Hey Doug,

I will attach an article that shows a step by step on how to accurately measure your leaf spring below. You'll want the trailer to be unloaded and measure from the center of the bolt hole to the center of the other bolt hole to get the accurate length. As well as being unloaded it is important to get one of the tire and wheels off of the ground for the best measurement.

If you want to let me know your measurement I can find the best leaf spring option for you.

Hey Doug, were you able to get the measurement for the leaf springs on your Forest River trailer? Once you have that length, I can help narrow down the best replacement. Let me know what you found so we can get you the right fit.
