The all-new 4.5" Coil Spring Lift Kits allow for even more ground clearance while going to a 37" tire.  Springing up to the new 4.5" lift yields all the bells and whistles of a big 6" kit but at a slightly lower, garage-able stance.  These kits come with heavy-duty steel radius arm drop brackets, heavy-duty fabricated steel front, and rear (2500 only) track bar brackets, forged dropped pitman arm, sway bar relocation brackets, and bump stop extensions preventing over-compression of the included Falcon 1.1 Monotube front & rear shocks.  Both 4.5" Ram HD kits include our unique CNC-machined 6061-T6 billet Aluminum Driveline Indexing System (DIS) that re-clocks the transfer case to properly align the front output shaft for improved driveline angles.  The Ram 2500 HD comes with the standard output diesel engine DIS system. 

Kit 49-19420 includes everything in our popular 6 lift kit as well as these new DIS re-positioning components. Heavy duty and great riding 4.5" lift front springs, 3" lift rear coil spring spacers, heavy-duty radius arm drop brackets, heavy-duty fabricated steel front, and rear track bar brackets, dropped cast iron pitman arm, front/rear sway bar relocation brackets and bump stop extensions preventing over-compression of the new Falcon 1.1 Monotube shocks front/rear shocks are all included in this premium kit.
