The lower you can get the body, the better your center of gravity will be.

Long shackles can give you some lift but they also can insert sideways flex which is, from what I hear, kind of scary. Plus, long shackles can screw up steering caster and the pinion angles on the differentials.

If you have 2 inches of leaf lift and the tyres will clear with that, I would - at the least - go back to the original shackles and feel how it rides. If it still feels like it is going to roll, It might be a good idea to remove the body lift.

As you can tell, I am more of a Spring Over Axle (or arched Spring Under) kind of Zuker than a lover of Body lifts and shackles...

I hope that this helps!

What size tyres are you running ?

Why do you need extended shackles ?

Have you done anything to address some of the problems from the shackles?

Do you need the body lift?

Have you pulled apart you leaf packs and played with the amount of leafs to get it flexing to or at least near the bump stops.

Seems like every mod you have mentioned will make the car less stable, albeit only a little with each mod , it would be cquite a lot all together.
The body lift won't be to bad , but if your running 30's or smaller then it's not needed.

The extended shackles will be doing all sorts of bad things , not to mention raise the whole drive line chassis ect. So if you haven't extended bump stops to run bigger tyres and longer shocks, ect I can't see any reason to run them. Not that I would any way. But there should at least be reason ither than full heck tic lift bro.

If you haven't already , pull the sting packs and remove some leafs to get it flexing better , will make the car less spooky and more stable.

I hope this helps.

How long have you been driving your sierra? Do you actually know its tipping point? If you're new to this, you'll be surprised how far they can actually lean.

My bet is you're getting wheels off the ground and that feeling is unsettling so you think its about to roll, but it probably isnt.

Here's my sierra with approx 5" lift, 31" tyres on 15x7-38mm rims at an angle, which i happily drove out of:

Go through the members section and you'll see many shots just like it.

It's totally normal to be lifting wheels up in the air, and the see-saw feeling you get when it happens is very scary when you first start hitting terrain that does this to your car, but keep at it slowly and you'll get a knack for the feeling, maybe even enjoy it! lol

What size tyre are you running, and on what rims?

Low is the new lift.

Cheers

Can't help with the clutch. I try and stay away from manuals. :D

30's don't need any lift at all, so any lift you're adding is just reducing stability. The tyres are responsible for 2" of lift by themselves. If you don't plan exceeding about a 31" tyre, I'd ditch the body lift.

31's fit with a 2 BL with no suspension lift at all. Or with no body or suspension lift with some guard work and bumpstop extensions. less height, and a car that settles onto its bumpstops are what makes a stable car.
