Springs are 25inch on center and 1 3/4inch wide. Axles are 34 1/2inch on center and hangers are at 29 1/2inch front to center and center to rear. Which kit would be best for my application?

For an equalizer kit that includes equalizers that are 5-3/4 inches long we have the part # AP233. This kit includes straps that are 1-1/4 inch though so you might be better off with the equalizers # TREQ104 and then the straps part # TRSL256.

For wet shackle bolts you'd want the part # 126B2.
