Expert Reply:

I do have an option for you but a 4" diameter axle is a 9,000 lb. axle. We do not have any over under kits for a 9,000 lb. axle. We can however piece together the parts that you would need.

- Replacement U-Bolt w/Locknuts for 9,000-lb, Round Trailer Axles # 11-64 (you need 4)

- U-Bolt Plate for 4" Diameter, Round Trailer Axles # 12-42 (you need 2)

- Spring Seat for Typical 9,000-lb, Round Trailer Axles # 3-51 (you need 2)

This would be enough for 1 axle, so if you have multiple axles then you will need a set for each axle. If your U-bolts and U-bolt plates are still in good condition you can reuse them and just pick up the spring seats. But we recommend replacing the U-bolts and U-bolt plates because they often times get damaged during removal.
