Flat Leaf Springs- Replacement Required?

Please see attached image.

I have noticed this at the beginning of last camping season and I ran it like this for a little over 800 miles since I noticed it. I am due for other maintenance and would like your opinion on whether or not I should add new leaf spring packs to the to-do list.

This is on a 2015 Eclipse Attitude 32SAG Toy Hauler w/ Lippert 6,000lb axles. I am not sure what springs to replace them with if I go that route.

  • Information on photo of tag is what I was looking for. It didn't do much good for me anyway at Lippert's website. They don't list the part number.
  • It looks like you have UNA-221 springs. You might find that number stamped on the thin tag wrapped around the spring pack. Spring
  • Okay I got the wheels off and dropped the axle.

    the springs have the following stamp.




    I had to run it through some filters to try and read the label better.
    Now i'm off to tryout my google-foo
  • Did you measure the spring as it sits in photo one?
    Place a straight edge across spring to get how much arc
  • Took another side off... seems to have better legible letters...

    still no luck searching google for me yet.

    bleh I dont know. I am hoping to find specs online so I can be sure what weight rating they are .
  • Here is a link to standard axles from Dexter. I know you have Lippett, but there should be direct replacement from Dexter.Springs
  • Call Lippert or Dexter and ask some questions. Maybe TSSB needs some info also 6K axles on a 14K RV? Sounds like an issue to me and maybe a recall with upgraded axles.
