2020 Nissan Frontier SV 4x4 with Ironman 4x4 Nitro Gas 2" Suspension Lift. https://ironman4x4america.com/nitro-gas-2-suspension-kit-suited-for-2005-2021-nissan-frontier-d40-navara-stage-1/
Had consistent vibration coming from the rear end between 40 and 50 mph. After researching this issue online, on the forums, and chatting with ADO it seems not everyone has this issue (or doesn't notice it....but I sweat everything) after lifting their truck. Those who have had it/noticed it stated installing shims like these helped.
These shims eliminated the vibration from what I've noticed. The angle of where the driveshaft connects to the rear differential is not as severe now.
I did have to drill out the center pin hole a bit to fit the leaf spring center bolt through but no biggy. You may just have to do this with the Ironman springs, not sure.
If you're experiencing vibration in the rear end after lifting your truck I would suggest trying these. They're relatively cheap and easy to install (thicker side to the rear).
