Which Way Do Slipper Springs Face on a Trailer

Question

Question:

I removed the old C-hook springs on my tandem trailer while I wait for the 4 new ones to arrive. I should have taken a picture because now I forget how they were arranged. Do the eyes face the front of the trailer and the C-hooks the back? Or are both eyes connected to the equalizer EZ loader type? I.e. is it eye, hook, eye, hook or hook, eye, eye, hook? Maybe you have a pic or diagram? Thx

With slipper springs you will want the eyes of the spring facing the front of the trailer and the open end facing the back.

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…

You are indeed right to think this way. When picking out the appropriate leaf springs for your custom built trailer you will want to choose them based on what the actual loaded weight of the trailer will be. Just make sure that the leaf springs…

You need to measure the inside portion of your hub drum. You need the width and depth like in the picture I attached. I can almost guarantee that you have 10 inch assemblies based on the 4 bolt mounting pattern though. So for free backing assemblies…

Slipper Springs like #e33SR do not use a bolt and bushing for the open eye end of the spring. It connects directly to the hanger using a slipper spring hanger kit.

Answer 12

Slipper springs do have a looser connection on the rear of them based on how they are designed. I am not sure exactly where the extra half inch of movement is that you referenced but if it's a vertical movement that's pretty standard. If you…
