Expert Reply:
Hey William, the leaf spring part # e94SR is for a 6k rated axle which has a 3 inch diameter so for a u-bolt kit you'd want the part # SP01-060. If your current u-bolts are in good shape though you can just reuse them.

Hey William, how did things go with the 3-inch U-bolt kit for your Forest River toy hauler? Did the new leaf springs fit well with your existing hardware? Your update could make it easier for the next person doing the same replacement.
