As opposed to Timbren's, I have become fond of SumoSprings. The ease of install and use as Timbrens, but the functionality of air bags. Install and forget and get a similar ride as a set of air bags. They are cellular foam rubber, so the act like air bags.
I couldn't stand the factory rake of my Silverado 2500. It was like a cat in heat. So I lowered the back with a set of McGaughy's drop shackles. That brought it to a little over 1" of rake when empty. I put on the Sumo's, and with about a ton of stuff in the back, the pickup then is right at about level. And what a smooth ride with the sumo's.
