SuperSprings SSR-117-40 | SumoSprings Rear for Ford F-150, Blue, 1000 lbs.

I was going to go with air bags for a number of reasons, but for the sake of cost and simplicityI went with Sumo's. They perform very well on my 2017 F150 by limiting lean, even when empty. They help reduce sway when towing and as well as sag. Towing is overall a better and more as stable experience. When empty, the small clearance over the axel keeps the ride the same as pre-Sumo (no spacer installed left about 1/2" clearance). I bought the blue ones, but if you plan on hauling full beds of dirt or heavy objects, get the heavier ones. A full load of dirt in my 6'9" bed will fully compress the springs. They still do their job, but they are maxed out.

Very easy to install. Took the sag out when trailer is hooked up.

My camper has the tendency to push the nose up and down on my truck over certain bumps. My camper is about 5,500 lbs and I keep the trailer level. It's a dual axle with very minimal things in storage compartments. I have the Roadactive coil springs installed. They help with body roll and absorbing the bounce some, but my truck would still bounce up and down. I think the short bed (5' 5") mixed with the truck being almost the same weight of the camper are the main causes of the porpoising effect, not tongue weight or height. I added these cushons and when I go over a bump, I don't bounce up and down several times. I bounce down and up once and the the sumo springs cushion/stop the next bounce. The sumo springs also reduced the bed drop with camper weight added. I went from about 1.5 inch drop to .5 inch. My ride with and without the camper didn't feel any more rough with the 1k sumo's installed

super easy install with 2 bolts for each. 1 bolt into existing hole that held the bump stop. Other into product itself. Great feel as it works like a spring and has give initially. The 1k lb is Perfect for my cab over camper. It weighed about 1400 lbs when first tested and now I have it down to around 1,100 and I think this will ride just like stock with the weight loaded. I have a 4x4 and did not use the spacer, so there is a 1" or 1.5" gap before it engages, so you get the stock feel cornering until it engages after 1.5" of travel. Better than airbags for offroad and handling, as people say airbags are boucy to shift the weight back and forth as oppose to working like suspension is supposed to and work like by absorbing and compressing without the rebound of airbags.

Directions said unscrew old and screw in new. (Paraphrased). Unscrewing the old bumpers was a major pain in the..... I managed to break free one of the welded nuts inside the frame. Both nuts must have been soaked in red thread locker. My gorilla hands didn't fit in the nearby hole in the frame. I ended up cutting off the bolt using a drill motor to spin the bolt and a mostly stationary hacksaw blade.After buying new hardened bolts and nuts I did eventually get these mounted after fabricating a custom fishing wire for the bolts and buying a few choice magnets. I lost a good 6 hours of my Fathers day making 2 trips to the hardware store in the course of my endeavor.I do however have to admit the end result was worth the effort. The truck no longer looks like I might be smuggling and its now much easier to control in high winds.

I have a 2012 Ford F150 Ecoboost and pull a 5000# dry weight camp trailer with a weight distribution hitch. I debated for a long time on whether to purchase the blue (1000#) or the black (1500#) Sumosprings. I think I made the correct choice for me with the blue (1000#) springs. I did not use the 1" spacer that came in the kit and I have a little over an inch space with no load and about an inch engagement when the trailer is attached. The trailer feels more stable overall. When loaded, I can feel small bumps more than before, but larger bumps are more controlled and feel more stable. I think it's a pretty good tradeoff loaded with no ride difference unloaded.

The instructions that come with the springs are really easy to understand. There is even a detailed list of all the tools needed so no crawling under the truck just to find out that you did not have the right tools. The installation itself is very easy. The set comes with a distance spacer for added stability. I opted to install without the spacer and could do that without raising the truck at all. Had I opted to install the spacer the truck frame needed to be raised about 1/2 inch.

Easy way to get rid of sag over rear axle when loaded. On my 2014 F150 STX 4x4 was about 1/4” above axle with spacer installed. Truck is a little more bouncy but most 4x4’s should be anyway.
