I think this is true and I want my Sumo's right at the axle resting plate or within a 1/2" or so, this is because I want my springs to start working rather quicker then later when the weight is added and they start to compress. I know every vehicle is different, but I would like to see no more then 1-1 1/4" of sag before the springs start working for my load range. I will call Sumo before I purchase them and have a full understanding of how this will work with my Ram and load range I will have when hitched.

Dealers don't want you to use air bags.

Look under most commercial 18 wheel trailers and you will see airbags. Dealers don't want to fool with the bags, but I have used them on tow vehicles for the past 50 years, and never had a problem. Always installed them myself, and the adjustability is awesome. I concur with two air lines so the load can be leveled side to side. Consider if you have a heavier load on one side of the truck and you can level that easily.

2017 Tundra pulling an Escape 21

We use Supersprings on our 2017 Tundra to pull our Escape 21 without an equalizer hitch. We have about a 700 lb tongue weight. We had them installed at the shop where we purchased them. As far as I know, there were no changes needed to the truck configuration to accommodate them. We really like the ride using them. We had the Timbren rubber spring enhancers on our 4Runner and when not towing the ride felt very stiff. The ride in the Tundra is smoother and about the same when towing and not towing.

I put Timbren bumper stops on my Transit Connect work van, which I run close to the load limit frequently. These were the lightest option. I think they work great once the body sits down on them. It corners very nicely with some weight on the floor; surprise. They are a bit harsh to transition with an empty van, but they work so well loaded up I don't mind.

We have a 2001 F250 SD 7.1L Diesel pulling a 38 ft Jayco Premier. Very happy with our Sumo Springs

I need to take pack some of what I said in this post. After receiving a PM from Russ, I went and looked at my truck brake lines. The driver's brake line runs between the super spring and the leaf springs. It looks OK. But the passenger side brake line runs over the super spring and the corner of the spring has started to cut into the line. Using a heavy duty tie wrap I pulled the brake line away from the spring.

Russ' PM saved me from a certain brake system rupture.

Its what makes these sites so valuable..and in this case preventing a pending disaster. So glad you took the time to observe your own vehicle.

Hopefully other Superspring owners will take note and make any necessary alterations.

I will forward to Supersprings and ask for their input.

well, I'd peg that brake line exposure as an INSTALLER problem, not an inherent problem with the supersprings.


on my Tacoma, the brake lines went nowhere near the Ride Rite airbags I had installed...



(the brake lines you can see going under the leaf springs were in fact secured there with a clamp, and do NOT contact the U bolt nuts that hold the ride-rites in place)

I did more research this morning. It turns out that the cut line is the parking brake cable casing and not the hydraulic brake line, as I originally feared. I put a clamp around the cut section. The parking brake cable slides smoothly, so I think I am good to go.

Anyone considering an airbag system, consider PAC Brake. I just purchased their air suspension system ( HP 10128...for 2019 Tundra). $100 + cheaper than Firestone and material seemingly more commercial like.
