Sagging Rear

[BackpackingDad]

I have a 2015 with 5100's set at .85 too. I installed the Airlift bags last week and it will lift the rear depending on how much air you put in it.
I will be loading up the truck in about a week and I think this will do the trick. With air in it, it stiffens up the rear spring nicely and improves the ride.

At about 80.00 it was a good mod.

Did you remove the rear Springs for your install? I hoping to avoid removing the springs if possible. Do you mind sharing tips from you install experience?

I installed airlift bags a few weeks ago on my wifes '10 Trail.

I unbolted the KDSS sway bar on the passenger side and took the shocks off, the springs basically fell out. Easy to slide the bags in with a little WD-40 or similar lubricant on the bench. I don't think it took any longer than trying to feed the bag though the coils.

I also installed Icon rear 2.0's and 2.5's up front and leveled the truck out. It lifted the front 1.5ish to get level.

I've got to say there seems to be more going on here. If your rear end is 1" lower than your front with the 5100'S adjusted to .85" you should investigate a little more.

I did remove the rear springs. Unbolt both shocks and the crossbar per the instructions and the springs come out easy. You will need to take them out to widen the hole for the air hoses and to cut off the bump stops. I had a lift so it was easy. Once you do that it's just a matter of taking your time. Simple install and well worth it. I took my time later and wrapped my air lines to finish it off.

There are definitely others more qualified on this forum, but here is my humble opinion. If you want to increase the rear height by as much as 1.5 inches, I would recommend you do new springs and no spacers.

Good call! I ended up going with Old Man Emu springs in the rear (mediums with no spacers). They lifted the rear a total of 2-3/4 inches, giving the vehicle a hint of a forward leaning rake without looking foolish. More importantly, the new springs have eliminated the "bottoming out" while carrying a load but they're not too stiff.

I just returned from a family trip to Colorado. Fully loaded 4Runner with 2 kids in the back. No sagging and the vehicle handled perfectly even on rough, winding roads.
