Sumo Srings for reducing squat when towing

[big-red-truck]

Hi everyone... I have a shiny new 2020 power wagon, just bought an RV (6800 lbs dry). I am NOT wanting to tow anything beyond the power wagon's specs, but I do want to reduce the 'squat' when towing. I heard that aurbags limit my ability to four wheel but sump springs do not. Do sumo springs work on a power wagon? I've seen videos of them working on 2500's but I am concerned about the sumo springs ability to work on the already lifted power wagon suspension

Thoughts?

Thanks in advance

I would opt for airbags with the Daystar cradle rather than mounting the bottom of the bag to the axle; you'll keep the articulation you want for off road.
I've had Timbren's before and they only help at a certain point and can be harsh. I considered Sumo's but decided I like the adjustability of airbags so I can adjust based on the load. I also like that the Airlift Ultimate have an internal jounce bumper so I can run empty bags (I normally run 5 psi when empty though), and if I pop a bag, I still have an internal bump stop. Airlift have a lifetime warranty.
I run Airlift 5000 Untimate on my 2500 for towing my 5W.
Good Luck, enjoy that PW!

Sumo Springs only have a 2-year warranty. Timbrens only reduce axle travel which is not a good approach.

Best solution is to add a set of SuperSprings at the rear. I increased the rear axle load capacity from 2800 lbs to more than 4000 lbs with a set and it took less than an hour to install them and did so with all wheels on the ground. At a cost of $445 they were a bargain and they will likely outlast the truck.

When an airbag fails the one on the opposite side is of no use. I cannot see having an air bag fail while traveling and having to cut short my trip. They only make sense for adjusting bed height when hauling a 5th wheel trailer.

I tried the Sumo Springs on my 2021 1500 2WD. They were too tall and only allowed a less than 1/2 in gap. Turned great ride into harsh ride. I had them on my 2014 F150 and they had a bigger gap therefore did not affect unloaded ride quality. I removed and replaced with Timbren's which now have about a 1" gap. Unloaded ride unaffected. BTW the Sumo's were a PIA to install. Timbren's much, much easier.

I have Sumo springs and they work good for me. Reduce squat, reduce poroising, help reduce roll.
No noticeable difference in ride when the truck is empty.

I had sumo springs on my truck and they definitely changed unloaded ride quality. They sit only 1/4 inch off the axle so every bump you hit they are connecting and adding a bit of jarring ride.

If you add springs/bags, make sure you also use a WDH. You can actually make your problem worse by just adding bags/springs without a WDH, because now your rear end is even stiffer making the leverage on your rear axle act as even more of a pivot, so your front end will lift more with a harder rear suspension unless you use a WDH in combination with that.
