Glad yours are doing better. It could also be poor QA/QC from Ironman....like buying a tool at Harbor Freight (sometimes you get a good one, sometimes it's a bad one!). If my front coils crap out a 3rd time, I'll get them replaced under warranty and see how long they last. If they crap out a 4th time, I'll switch to Dobinsons and be done with everything Ironman.My ironman4x4 coils and shocks (nitro), installed back in 2021 are still going strong with over 65k miles on them. I haven't noticed any sagging, and have added additional weight since then (front bumper and winch, sliders and skids). I do find the coils a bit stiff, I got the 'medium weight' version, they ride better when weighed down a bit.
Here is a photo of my 4-year old rear coils next to the new Dobinsons coils from last year.
DIY shock rebuild - IMO by far the best part of these shocks.
