Rancho has engineered and built this kit in the traditional method that drops the rear torsion bar crossmember down. The torsion bars will hang down farther than stock and are visible once the truck is lifted. If you prefer having the torsion bars up and out of the way Rancho also offers a Torsion Bar Relocation kit under Rancho part number RS6554B.

This Rancho 4" suspension lift increases front vehicle height by a minimum of 4" inches in the front and levels the rear. This kit even works with OE wheels and does not require any exhaust modifications! This kit will fit all 2011, 2012 and 2013 model year 2500HD series Gasoline and Duramax Diesel equipped trucks, including those equipped with the Allison transmission. Please note, this lift will NOT fit the older 2010 HD series GM trucks!
