I bought this kit a few months ago and I absolutely love it. The ride quality is the same thanks Suspension Maxx. I wish I can add a picture but you can't see it here: https://youtu.be/9JPT0mFTyyU
just purchased a 2020 GMC sierra denali 1500 with adaptive ride control. I want to haul a heavy trailer with it but need air bags to raise the rear from sagging. Please advise. Thank you. Russ
Love the product! Leveled my 2019 Denali and kept the factory ride quality.
