I have these springs in the rear of my C10. I've also had the ECE 5" rear springs in the past. To me, these 4" HD springs are far superior to the 5" springs. My truck was also bouncy with the 5" springs, and forget putting anything in the bed. The 4" HD springs feel much more balanced and pair well with the 3" springs I have on front. I've also loaded up the bed with about 600 lbs of scrap metal before and the springs handled the load admirably. I was hesitant to add more weight at first, but after driving it I know it could handle more. Granted, this is all for my shortbed, so I'm not exactly sure how they'd feel in a Suburban.
