How to Determine Correct Replacement Slipper Springs  

If you can get me your axle capacity I can let you know which leaf spring would work best.

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)…

A Nylon Bushing #TRBU11561 is not required to be used on the open end of the 4-Leaf Slipper Spring #e33SR. Since the bushing is not going to be fully encased it stands that under the weight of the trailer it will fail and break apart more easily. I…

For hanger kits you'd want the part #APS3SE which comes with everything needed to mount the leaf springs #e33SR. We don't have equalizers that fit 1-3/4 inch wide springs so you'd not use them.

Based on what you have described and the measurements you have taken I do believe that slipper spring #e33SR is correct. The #e33SR length is 26-1/4 inches so the mid-point length of your existing spring is on par with that. The old springs have…

Since you have a C hook type spring you really need to replace it with another C hook unless you are okay with replacing all of the spring components. We only have one c hook spring as of right now part #e33SR, but it has a 4,100 lb axle capacity and…

The 26-1/4 inch measurement of #e33SR is taken center on center from one bolt to the other. On the diagram I've attached it's measurement "C". This is the measurement you'll want to make on your springs. Then find the same…

Most likely, the trailer would be rated for 7,000 pounds gross if it has two 3,500 pound axles. But there should be a sticker or plate somewhere on the frame near the front of the trailer that lists its official capacity. Also, the trailer can only…

In order to determine the torque rating for the lug nuts on your trailer you will need to know check out the chart I attached that shows all of the torque specs for all the trailer lugs available based on stud size, wheel material and wheel size.
