Upscale Automotive has also developed some custom rear springs to improve the Sprinter ride. I kept the springs they removed during the Glide Rite
install. I got a call a little while later and they wanted to use my springs as reference for the new ones they were developing.
I'd give them a call. They also upgraded our rig with Koni's all around and a larger rear sway bar. Not sure the heavier sway bar is actually needed unless you have a more heavily loaded Class B+ or C.
Jon, who installed our air suspension, Konis and did some other work on our van has since sold the business. (IIRC) The new owners appear to be committed to their customers as well. We met them at the Sprinter-Fest and were impressed with their automotive experience and enthusiasm for the Sprinter and other vans entering the market.
For our 2010 3500 170, we also went with Alcoa wheels and a slightly larger Michelin MS2 tire. We run them at about 55psi cold. The ride is very good even in the back. I might put the lighter OEM sway bar back on someday because ours is a cargo van and our conversion
is light so we have ~1000lbs of our GVWR to spare.
If you replace the tires, make sure your tire dealer lifts your Sprinter in the proper manner. Otherwise, they could damage your vehicle. We do all of our tire business at Discount Tire in Gresham, OR. They install upgraded wheels and tires for Outside Vans and so have the necessary experience.
All the best,Hein
