Review on SSR 130 47 SumoSprings Rear Ford 350 by Sam Bhushan

I purchased SumoSprings front and rear wheel kits for my 2012 E-450 based RV. The front assembly went smoothly - a very simple assembly that took about 10 minutes per side. With this product - the rear kit - it's a completely different matter. The frame mounting flanges were too wide to slide into the frame rail channel section left over when the factory fenders were removed. I don't know if there is anything unique to my car but the listing says it is suitable for direct bolting. Definitely not. I checked the fit and proceeded to grind the material on the spring loaded vertical flange sections to reduce their width to a suitable width (at least 1/8 inch). I also added a larger radius at the end to match the track frame. Inner radius such that the spring mounting surface is parallel to the axis of the axle. Not much fun since I did it on my back and not on a lift. I didn't want to sand too much material so I kept checking the fit and removing the mounts after removing some material - I'm guessing at least 7 or 8 times on the first side. Based on what I learned from the first side (passenger side), the driver side went faster. I may update the review when I ride under my belt for some time.
