Hey Matt; for leaf springs what you want is one that at least meets the axle rating of your trailer, so a 5,000 lb spring won't work. Instead, go with the 5,300 lb or 6,000 lb springs. That said, we don't have anyway of knowing exactly what leaf spring is on any one trailer, so you will have to do just a bit of measuring.

All you need to do is measure your current leaf springs from center-to-center of the spring eyes, and leaf springs also flatten a bit over time, so you can go with ones that measure just a bit shorter than what you currently have. The number of leaves also isn't an object, so you don't have to get a 4-leaf spring even though that's what you have.

So for example, if your leaf springs measured 25" you can go with the 6-Leaf Double-Eye Spring for 5,300-lb Trailer Axles - 24-7/8" Long # e76SR. Or if they were 25-1/4" you can go with the 4-Leaf Double-Eye Spring for 6,000-lb Trailer Axles - 25-1/8" Long # e47SR.

I have added a link below to our entire selection of 5,300 lb and 6,000 lb leaf springs, which you can filter through by length.
