Reduces Rear Sag, Sway, and Instability when Towing and Hauling

Sway and sag are always a threat when you're towing with your 2009-2020 F150, even if you are well shy of your GVWR or GCWR. To help minimize sway and sag, SumoSprings has developed with 1500lb SumoSpring Kit. Capable of holding up to 1500lbs of load, the SumoSpring System consists of drop-in extended bump stops made out of specialized microcellular urethane material that gives you the load support of a traditional air spring, but with a much better street ride and without the hassle of filling up the springs with air every time you load up your F150 or trailer. The 1500lb SumoSprings Kit is extremely easy to install and drops right into the factory bump stop location in only a matter of minutes. The SumoSpring keeps load off your truck's suspension, minimizing sag and rear-end roll so that you get vastly improved stability without hassles.

Unique Microcellular Urethane Springs with Brackets and Spacers

The 1500lb SumoSpring Kit includes a pair of mircocellular urethane springs, brackets, and spacers work together to give your F150 a vastly improved loaded ride over stock. Each spring features a black color that denotes its -47 urethane density that can handle 1500lbs of load at 50% compression and holds enough air to handle heavier loads than the blue SumoSprings while still giving your truck a nice ride. The SumoSpring features a full memory rebound after compression so that you don't have to worry about resetting the spring or losing load capacity over time. The patented microcelluar urethane construction provides your F150 with a smooth, progressive spring rate with excellent damping characteristics in both loaded and unloaded applications. These springs are made right here in the USA.

2015 f150 5.0 4x4 extended cab

it helps with squat, but if you go over a series of pot holes or train tracks, or any kind of off roading, i have found that they make the rear end almost hop around a lot more when the truck is empty, sumo said well it sounds like you need rear shocks, didn't have this issue before the install, but against better judgment I replaced rear shocks with some nice bilstein shocks and as suspected didn't change the hop, if you're going around a corner fast and hit some pot holes it will grab you're attention very quickly like driving on ice.

I LOVE these. I installed them WITHOUT the spacer, so I have an inch of suspension travel that is completely stock. Loading a 700 lb tongue weight trailer only squats about 2" at the rear fender. This trailer is a 26' travel trailer, and I noted a significant improvement in sway and rear planting with the addition of the Sumos and Bilstein 4600's. One poster noted hop over small rapid bumps (train tracks), and I initially noted this also, but removal of the spacer resolved the issue for me.

The bump stop same as airbag. They hold air or just a made out of a solid material? I haul 210 gallon barrel sometime a 275 just needed something to help with the weight and sag. don't want to add helper spring cause it raises the rear end and have bad ride. have a set of helper spring and just hit my frame when driving off road with a load of water, don't like to deal with airbag also want a stock look when you look under the truck.

The SumoSprings are not the same as springs. The SumoSprings are essentially extended bump stops made out of a unique microfoam that still lets the axle articulate, but also provides some additional load support by preventing squat.

I have a 2012 fx4 with a 6 inch lift. Will these work? What is the best option the air bags or these

Asked by: Brandon Eric Wright - 5/15/2020

As long as your lift kit of choice didn't modify or otherwise change the factory bump stop mounts, then the SumoSprings will work on your truck. No option is really "best". Air Springs or extended bump stops really comes down to how much you tow/haul, how often you tow/haul, whether your lift kept any rake, and whether or not you're willing to sacrifice any on-road ride quality for improved loaded stability. If you don't tow a lot/often, if you don't get a ton of rear rake when towing, and you want to keep as much ride quality as possible, then the SumoSprings are the way to go.

What is the length? Can they be used with a Roadmaster active suspension kit?

Asked by: Jim - 5/15/2020

The entire spring assembly is roughly 9.5" tall if you include the optional spacer, and 8.5" without. We have not tried the combination ourselves. Since the SumoSpring sits inboard of the leafs and contacts the axle, you can likely use the RAS in conjunction with them. However, we can't 100% guarantee that you won't have to make some custom modifications.

How do the blue and black springs compare? I haul an 850 lb atv and want to reduce the drop in the rear and want to know if I'd be better with the 1000 lb or 1500 lb set.

Asked by: clees606 - 9/8/2019

We have yet to try these out as of yet, though we are hoping to get them on one of our project trucks for testing soon. On paper, the lower-rated Blue Springs will ride less stiff if your axle does come into contact with them than the black. In theory, you would be fine going with the 1000lb-rated springs, though you would get less sag with the 1500lbs springs, since they are a touch stiffer.
