Better Than Air Bags

Installed Sumo Springs (SSR-207-47 Airless Air Bags) on a 2017 Silverado 2500HD (Z71 with Rancho shocks) this morning. Yes, Revain points out that this is the wrong part, but it is. Probably one of the easiest installs I've ever done; Up to 30 minutes cleaning! The truck is parked with a 2,100 pound retractable camper in the back and currently sits flush front and rear "in front” of the Sumo Springs setup. Take this into account for the numbers below. The RV's weight lowered the body 3 inches at the stock spring fenders; he had just started touching the transfer sheet. Once installed, the Sumo springs made contact, compressing 0.25 inches and raising the truck 0.5 inches at the rear fenders. So you're under full compression time, but not by much. As advertised, Sumo Springs can compress up to 80% of their 6-inch length; At 50% compression they lift 1500 pounds (heavier available) for a consistent ride height when heavily loaded. Driving makes "heavy" sharp turns back and forth (low speed) and bumps; almost NO road roll and judder, they cushion spring compression/bottoming from road entry to smooth transition/feel. Yes, I think they're better than the Firestone airbags I put on the "latest" truck; not elastic, elastic. I ended up installing 2.5 "Rancho "adjustable" shocks and that took care of the airbag rebound. Observations from my personal experience and I hope this helps you decide how to raise the ride height or the " Roles" can be controlled when loading. After more experience with Sumo Springs, I can increase my rating to 5 stars.
