Expert Reply:

If you are dealing with a single axle and the 4-Leaf Double-Eye Spring # e97SR I recommend either the standard Kit # K71-403-00 or Wet Bolt Kit # K71-358-00 which will give you new bolts, nuts and shackle straps. The U-Bolt Kit # CE23002 is a great upgrade to the uncoated u-bolt you currently have.

If you have a tandem axle trailer you would use 2 of the U-Bolt Kits # CE23002 and one of the wet bolt kits from the list below depending on the length of your current shackle straps and if you have the Correct Track suspension. If you are unsure of what correct track is then simply look at your leaf spring hangers and if you see they allow for any adjustment front or back with a plate inside the hanger then that is correct track.
