Air Bag Helpers, Dual Valves or "T" Fitting and Single

[Mr Nick]

Not exactly a "Pro Touring" question, but I'm hoping some of the suspension gurus here can help.

Daily driver 2018 Durango R/T, I replaced the factory Load Leveling rear shocks with Bilstein "normal" shocks. This lowered the rear a touch for a better look, but also removed some effective spring rate and the rear end was too soft. I installed Air Lift bags inside the springs and with about 15 psi the ride is much better. I used a "T" fitting and a single valve.

But I got to thinking... with a T fitting, wouldn't the air bags act the opposite of an anti-roll bar in corners? Turn left, load right side suspension and the bag compresses some, the increased air pressure then causes the left bag to expand and increase body roll. Once a find a PSI I like, would it be worthwhile to remove the T and have two valves so the bags are not connected? Does it even matter in a daily driver, non-performance application? Hmmm...




Thank you.

You are correct, it acts the opposite of an anti roll bar.

I would say if you haul large, top heavy things, it might matter. (the SUV is a little top heavy anyway).
If you don't, it's typically fine and not noticeable.

Then again, one Schrader valve and a little airline is pretty cheap.

I always split them.

Thank you both. Once I find the PSI I like, I think I'll split them and see if it makes any difference.
