When picking out a leaf spring you really want to base it on the capacity of the axle and the length more so than the amount of leafs in the spring pack. If you can get me the axle capacity of your trailer and how long you need I can get you the best recommendation.

If you have a 4,300 lb axle and need a 26 inch long spring though the part # e33SR is your best option overall and would work great.

Answer 9

As they wear, leaf springs tend to flatten out. The first step is to get the correct length of the existing springs. In order to do that, you'll need to put the trailer up on jack stands and measure them (center eye to center of the slipper) with…
