More Control for the 4.5-Inch Ram 3500 HD
ReadyLIFT has upgraded its 4.5-Inch Coil Spring Lift Kit for 2019–2024 Ram 3500 HD High Output Diesel 4WD trucks with four vehicle-specific Falcon 2.1 Monotube Shocks. The result is the big-lift stance and 37-inch tire clearance Ram owners want with improved ride quality, stability, and control.

Build a more aggressive Ram 3500 with clearance for up to 37×13.50 tires on the recommended wheel setup.

Application-specific engineering
ReadyLIFT Driveline Indexing System
The included CNC-machined 6061-T6 billet aluminum Driveline Indexing System re-clocks the transfer case to properly align the front output shaft and improve driveline angles at the increased ride height.
A transfer-case clocking ring, heavy-duty transmission crossmember, and supporting relocation components work with the suspension corrections to create a complete system for the High Output diesel application.
