Description

IMPORTANT NOTICE: Will not work with Factory Air suspension or Auto Level system.

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.

Details at a glance:

* For use on diesel engine Ram 2500 4WD HD trucks only
* All-new 2019-2022 Ram 2500 4WD HD 4.5 in. lift kit
* 4.5 in. front/3 in. rear spring lift kit
* Includes all-new transfer case clocking ring and new heavy-duty transmission crossmember
* Includes four Falcon 1.1 monotube shocks tuned specifically for the Ram 2500 HD
* Allows for up to 37x13.50 tires on 20 in. x 9 in. wide wheels with -18 offset.
* Note: Does not work with Factory Air suspension or Auto Level system (factory helper bags)
