The trick for hanger spacing is to subtract around 3/8 of an inch from the spring length (eye to eye) and then use that dimension for the hanger spacing on a single axle trailer.

So for a 23-1/8 inch long leaf spring a spacing of 22-3/4 inches would be the correct dimension to use.

Answer 8

For your double eye springs that are 25-1/2 inches, it is likely your hangers are 29-1/2 inches apart on center and your springs most likely were originally 25-1/4 inches as they will stretch slightly over time. For instance if you were to use 25-1/4…

Answer 9

The recommended clearance with leaf spring suspension on an unloaded trailer is between 2 - 2-1/2 inches. You should have sufficient clearance with your loaded trailer, as leaf springs only tend to deflect 1-1/2 inch when carrying a load.

If your Double-Eye Leaf Springs are 27 inches long, you will just want to mount the hangers in the Redline Single-Axle Trailer Hanger Kit #APS4 mentioned in your question about 26-1/2 inches apart. As a general rule, you want the distance between…
