The one I installed isn't an airbag though. It will utilize the same principle of an air bag, that being compressing air within a rubber containment "thing". The Sumo springs rely on the air within the product itself..the walls...bubbles within like an Aerobar. lol One thing I can't do with mine is increase the air pressure to change the weight carrying capability of my truck but they will help me carry what I'm carrying already. Thus I put them on my truck. Like I said in a previous post...I didn't think I needed them as we did our first trip out before I got delivery of the product. But for a 1/2 hour install time....I figured I would test them out anyways. I like what it did to my truck empty....now let's see what it does with my (our, sorry) trailer. Sumo will still be willing to take them back if I'm not happy with them or do not see an improvement in my truck/trailer handling.

I like my odds on that!

Which model did you get? I see 2 listed for our trucks, one has a 1,000# carrying capacity and one is 1,500#.

I'm curious to see how they work for you. My comment was more of a flashback to a spirited debate I seem to recall where an axle borne auxiliary spring was deemed a really bad thing for towing with a WDH (which they are not). It would be interesting to set those Sumos up in a press with a scale to map out their effective spring rate. Do they provide any such info?

"The capacity of SumoSprings varies depending on the height, diameter, and density of the spring. SumoSprings are rated by how many pounds of pressure it takes to compress the spring down to 50% of its original body height. You can view a SumoSprings capacity in the Product Guide, Application Guide, or in the Official SuperSprings Online Shop product additional information tab."

The 2 models for the F150 are rated at 1,000 lbs and 1,500 lbs so that would be the weight it takes to compress the springs to 50% of their overall height. They are a progressive spring so they should ride well at lower compression but gain strength quickly as you load the truck and it starts to squat.

Similar to Timbrens. Looks good

Liking what I am reading, so I too want to know, which ones were installed.

Subscribed for updates. I'm swapping bilsteins this weekend to help smooth out towing and these sumo springs seem like a great idea to help combat the jarring bounce when loaded down and you hit just the right hump.

I routinely carry my ATV in the bed (900lb) plus family and a 1800lb GVW trailer, or my 6000GVW camper and a motorcycle or two in the bed. I bought my 150 to tow!

get supersprings. they are floating till load. also adds roll control loaded or unloaded. they can be installed as non-preload or preload. and yes i have years of experance with both super springs and sumosprings. i got my first set of sumosprings in 2007 or so when i dropped my 05 screw f150 6". i pretty much rode on the sumo springs for 150+k miles. no more jar from tapping the factory bumpstop over a speed bump. and regularly put 1k in the bed.
the supersprings were put on my 14 lariat heavy duty about a month after having it. needed an alignment after. i used the truck for 44500 miles. worked it for 7 month moving pallets. from 100lbs up to 2500lbs. with the super springs i had a 2" drop in the rear and 1" in the front from the +2k loads. there is nothing on the market that compares. also makes the ride very stable. so much so i am still not used to the body roll on my new truck after 4500 miles. but i can't put supersprings on it lol. would kill the off road ride. the same roads that are winding i drive 40-50 mph where i used to drive the 14 at 55-60mph.

I installed the SSR-117-40 on my truck, which are rated for the 1000# capacity....I think. I am not into trying to get my truck to handle more weight...just help me with what I am carrying already...which I found the truck to do very well at anyways. But these are awesome...even when just truck and empty.

I think I finally have time to hook 'er up this afternoon and take it for a drive. My wife would like to go along to see the difference and it would be a typical traveling load for us.

There are not many straight roads here on Vancouver Island, especially in our area. I've noticed a great change in the stability of the truck with the Sumo Springs to the point I have to becareful I don't take corners too fast. LOL It's still weird to not have body roll in a corner.

I will be reporting tonight on the tow test. Standby one!
