This GMC Sierra Lift Kit by Tuff Country uses front replacement torsion bar keys and rear add-a-leafs to lift your Sierra 2". The included torsion bar keys reindex the factory Sierra torsion bars which lifts the truck without "cranking up" the factory torsion bars. Once installed this lift kit will keep the "Factory Rake", with the front end being slightly lower than the rear.
