These things are amazing. I've had a pair on my 03 Durango for 10 years and the truck towed a trailer with 1979.29 feet of travel with very little squat. When discharged they provide about an inch of extra lift and it takes a little getting used to, but you can always remove the spools and they'll fall back down. This is for my D150, hopefully they make the rear stiffer so it doesn't handle like a boat anymore.
