Great product and easy installation. These have helped quite a bit in reducing the sway in our 25’ class C. Very easy install with simple hand tools and a bottle Jack.

I purchased both the front and rear sets of SumoSprings for my 2012 E-450 based RV. Front set went on without any issues - very easy install that took about 10 minutes a side. This product - the rear set was an entirely different matter. Frame mount flanges were too wide to slide into the frame rail channel section exposed after the removal of the factory bump stops. I don't know if there is anything unique to my vehicle but the listing claims a direct bolt up fit. Definitely not the case. I checked fit and proceeded to grind material away on the spring mount vertical flange sections to get them down to a width to fit (at least 1/8"). I also added a larger radius to the end that mated up to the frame rail inner radius to get the spring mounting surface parallel to the axle line. Not fun - as I was doing this on my back, rather than on a lift. I did not want to grind too much material away so I repeatedly checked the fit and removed the brackets after the removal of some material - I suspect at least 7 or 8 times on the first side. Based on what I learned from the first side (passenger) the driver side went faster. I may update the review once I have some driving time under my belt.
