When replacing the leaf springs on your boat trailer, you will need to match all of the dimensions and the spring capacity as closely as possible to the original spring. Typically the measurement from eye to eye will lengthen and the height measurement will decrease with wear. I have included a picture that will show you the measurements you will need to match to replace your leaf springs.
From what I could find on your 2017 Karavan boat trailer, it has a GVWR of almost 5,000 lbs. So at the least you would have a 5,000 lb. axle. which would put you into leaf springs like the 4-Leaf Double-Eye Spring for 5,000-lb Trailer Axles # e44SR.
I have linked our selection of leaf springs, so after you get the measurements you need and find your axle capacity, you can select the correct leaf springs.
