Its been a 2+ years now and still no issues.dig the simple build. im surprised you experienced no driveline issues with the amount of lift you have on there.
I did get a 3 year alignment package through my local tire shop.
So I take it in every 4 months for a quick alignment while I wait. But thats about it. And honestly, that might be overkill.
I haven't really noticed anything wrong and I do take it up jeep trails semi-regularly.
Thanks for the kind words!
