This Tuff Country 2" Lift Kit for the GMC Sierra 2500HD truck uses front replacement torsion bar keys and rear add-a-leafs to lift your Sierra 2". The included torsion bar keys reindex the factory 2500HD 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.
