You want leaf spring shackles to be at a slight angle as that prevents the springs from flipping around to the other side of the equalizer over uneven terrain.

I contacted MORryde and this does happen from time to time as the weight of the trailer can spread out the axles due to downward pressure on the springs/suspension. Odds are the 35" wheel base #MR27ZR will be the correct one for you, but they…

Good question, and what happens is that leaf springs elongate over time, and since you mentioned you got measurements of 25-1/2 inches from center eye to center eye and 26 inches under partial load, the best option for leaf springs really is the…

Answer 10

The varying heights of the hangers is all designed so that you end up with the leaf springs as level as possible and still end up a desired distance away from the trailer frame. It may seem odd, but the center hanger will stick down further because…

Answer 11

If the outside width of hanger #E4139 is 2-5/16 inches and the metal thickness is 3/16 of an inch then you would take 2-5/16 and subtract 3/16, and then subtract another 3/16, to get 1-15/16 inches. It is meant to be used with leaf springs that are…

I attached a picture that shows the proper position of shackles and equalizers on trailer suspension. Sometimes the shackle will flip up but if you jack up the trailer by the axle that's got the shackle flipped you can usually get it to flip back…
