ReadyLift Suspension Coil Spring Lift Kits (4.5 in.)

The all-new 4.5 in. coil spring lift kits allow for even more ground clearance while going to a 37 in. tire. Springing up to the new 4.5 in. lift yields all the bells and whistles of a big 6 in. 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 and rear shocks. Both 4.5 in. Ram HD kits include ReadyLift Suspension's 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 ReadyLift's popular 6 in. lift kit, as well as these new DIS re-positioning components. Heavy-duty and great riding 4.5 in. lift front springs, 3 in. 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.
