Cool burb.
I saw your suspension thread.
You have alot of issues going on back there.
If you want to keep that ride height,... you will need to spend some money.
Call ECE (

They know these trucks.
Buy a set of 6" drop springs, a set of rear shock relocators, a Super Track bar, and a set of their drop shocks.
The shock relocators will stand up the rear shocks so they will actually work.
The super track bar will re-center the rearend.
Right now the rearend of your truck is off center in the frame.
You have no suspension travel also.
I would add a bolt in c-notch.

Then add a 1.5" lowering block.
(no more than 1.5" unless you switch to bigger diameter wheels and add air bags)

Fix the rearend and it will ride good.
But you can't ***** about the ride if you don't fix it correctly.
Good luck.
My truck is at 5.5/7.5 static drop.
So the rear of your burb will be this low on 15" wheels.
Any lower will require a step notch in the rear frame rails.
