Front lift options
 

I want to put a 2" lift add a leaf on my Bravada, then do the torsion bar 2" lift on the front. Is there any other method of lifting the front possibly another 2"? 'Cuz if there is, I can throw the shackles on the rear also and get a 4" lift.

Nope. Just crank the t-bar adjusters to get about a 1.5" lift up front. I personally do not recommend using indexed t-bar keys like in the Rough Country 2" lift. You could always shell out the big bucks for a 6" lift but then you will have to do something about that all-wheel drive, no low range case of yours.

Could also do a 2" Body lift which will give you plenty of clearance to offroad some 31's with no trimming, 32's with quite a bit of trimmings.

There is only about a 0.5" difference in ground clearance with 31" tires and 32" tires, I'd just stick to lifting it 2" and putting on 31's.. Cheapest and Safest way to go.
