For use on New body style Ram 1500 4WD with Factory Air Suspension. Not for use on classic body style Ram 1500. ReadyLIFT offers several different leveling and lift solutions to properly enhance the stance and driving quality of the 2019-2023 Ram 1500 truck 4WD. Like the body design, the suspension design of the 2019-2023 Ram 1500 4WD features some unique design elements that differ from the previous generation Ram. These differences were tackled by our engineers as a result, we now offer a High-strength fabricated offset steal spacer - bolt on leveling kit to properly level these new Ram 1500 4WD trucks. The 66-19150 kit provides 1.5" of front leveling lift in the form of our popular CNC machined billet aluminum top mount strut extension. The 2019-2023 Ram now comes with a composite upper control arm with a sheet metal cover. Our engineers determined the stresses around the ball joint would be too great for a traditional strut extension leveling kit. To add strength and security to your new leveling setup, we have developed a new heavy-duty DOM tube steel upper control arm with corrected ball joint angle cups for proper pivot angle. Our 66-19150 1.5" front leveling kit will get the job done right and affordably. This kit is for use exclusively on air-suspension equipped trucks.
