Will the load leveling shock hold up as well as air bags for your travel trailer?

 

Technically, with the WDH I wouldn’t need either of these. I’m just trying to take care of the truck and give the rear leaf springs a helping hand.

The air bags will be fine. Theee caught my attention as they’d simplistic, less to fail.

 

I don't have to have help with my TT either, it towed home 185 miles just fine. I also have a WDH and had a little more squat than I wanted, so this weekend I installed a set of SumoSprings. Like you said, gives the rest of the rear suspension a little break and is a maintenance free, no mess/adjusting with it item.

 

How do they ride unloaded? Do they also give you a little more rake when unloaded?

 

No, I had mine set with the spacers, which was just over 1/4" away from the axle. After driving for 2 days that way, I determined that big bumps were too harsh. Just removed the 1" spacer and took it over some rough spots pretty hard and it's back to riding like stock. The idea is to let the preload off the leaf springs and have the Sumos maintain contact 100% of the time when fully loaded. This will do exactly that as I read on a towing forum a couple nights ago that you want about 1.5" of travel before contact. We will see how I like them after the first trip to the lake.

 

I messed up on my Sumo Springs install. I ordered 4wd springs cuz they are taller and even used the spacer when I first installed them. I figured having them in constant contact with the axle was going to be good. 'Twas not. Harsh bumps as the foam is very rigid. The I removed the spacer. That still lead to harsh bumps over large bumps as Summers mentions. I ended up cutting the bottom "spring" off the foam so they only come in contact with the axle when I load down the bed. I should've stuck with the 2wd versions and without the spacer.

 

I ordered the 4x4 version since I am RWD but have a 2.5" level and OEM 1.25" blocks in the rear.

 

Nearly same here. 2 inch level, 1.25 rear blocks added to my 2wd.

 

I can measure, but I am close to 1.5" of space between the Sumos and axle. I wasn't touching even with the spacers as I installed them without lifting the truck at all, just climbed under it.

 

Last time I looked at them, my driver's side sit a little closer to the axle than the pass side. Figured the weight of the tank being on that side. No biggie. I threw a stall mat in the bed to 1) help protect the bed and 2) the weight added calms the light rear end some. The factory bump stops will probably never make contact with the axle unless you jump your truck with a lot of weight in the bed. LOL
