I have a sloght lean problem with my truck (its 2006 gmc sierra single with a 3/6) i alright have the front driver side situation planned out already. All thats left is the rear driver side it hangs abiut an inch lower than the passanger side. I have a 6" flipkit does anyone know if its oky to add shakles with 6" flipkit? I want to add for 1" drop on the lower side and 2" on the passanger side but dont know if itll work

Are you sure the problem is in the back? A truck can not be lower on one side in the back and the front is straight. If so, it is bent.

It’s a NBS Chevy thing. Gas tank, battery, all wiring, plus driver is on the on driver side. They always tend to be .5” to 1.5” lower.

Having a stock and 1” drop on the pass, or 1” and 2” is pretty common.

Many cars/trucks are heavier on the driver's side. The stiffer or higher the spring rate, the less this would be a problem.
So If it is sagged out more than an 1", I'd say the springs are too soft anyways.

I would not change anything suspension geometry related. Either leave it alone or rearch or dearch one leaf spring a tiny bit.
