Got a few questions as I hear a few things and trying to figure out fact from fiction... I have an 05 1500 4x4 Suburban w/ 1k helper bags in back. w/ 33's".

1) Which would give best 2-3" lift, using Ford keys, GM 1500 style lift keys or installing 2500 torsion bars ?

2) If using 2500 torsion bars do I need 1500 keys, 2500 keys or 2500 style lift keys ?

3) has anyone put 35" with ONLY key style lift ? I'm willing to cut fenders and bumper w/ fender flairs to cover up hacking job LOL...

As I said I lifted it 1-1.25" to get the 33's" to fit and want to go between 2-3" to get 35's in there but hope to learn what others did to get there without using expensive lift kits and just doing a key style lift in front and adding a block/ring to rear spring + my airbag on rear lift.
