These are decent. I wasn’t expecting to level like actual air bags but the don’t really support much more over stock. I tow a 22’ bumper pull travel trailer and it had the same affect with it without. The only noticeable change is when empty hitting a bump I can feel it seems a little more stiff.

I like the fact these don't require air pressure. Installation was fairly easy, just needed to be careful to avoid wiring. They seem to work really well.I wanted to lower the back end of my 2015 Colorado pickup (all these newer trucks have too-tall beds!)So I removed the bottoming leaf spring which dropped the bed a bit, and the addition of Supersprings keeps the ride low, but prevents bottoming of the rear suspension!
