I have a stock 2000 LS4x4 wanting to add a suspension lift. Does anyone know if this will give me 1-3 in in the rear or the front. Without anything else. And if I do need something else what is it?

 

The leaf shackles will give you 2" in the rear. The torsion keys lift the front without bottoming out the adjuster bolt. Front will be adjustable but 2" is the most you should go. Rough Country has a kit that comes with new upper controls arms to help with alignment and ball joint wear and a differential drop bracket to reduce angles on the cv shafts.

 

look for the package deal there cheaper then buying them seperate
