You can get them reset or rebuilt, but it's not cheap. I went with adjustable air shocks instead.
Contact Evan at Delica Works Intl. He can help.Unfortunately, my leaf springs are broken, not just flat. The part that wraps around the shackle bolt broke.
The only contact I have is via facebook, sorry. They are working on their website; https://www.delicaworksintl.com, try and contact him through there.I don't want to create a Facebook account, and he doesn't seem to have a website. Can you supply contact information?
