4.5 Inch Lift Kit w/ Radius Arms | Ram 2500 (2019-2024) 4WD Diesel | FOX 2.0 Adventure Series Shocks | Zone Offroad

Configured with FOX 2.0 Adventure Series IFP shocks featuring an internal floating piston monotube design, large 5/8-inch hard chrome plated heat-treated alloy steel shaft, race-developed high-flow piston design, application-specific valving, and a long-lasting silver coated finish for improved ride quality and off-road performance.

Overview

This 4.5 inch lift kit is engineered specifically for 2019–2024 Ram 2500 4WD Diesel trucks. Up front, a pair of progressive rate, diesel-specific 4.5" coil springs provides the extra height and smooth handling across demanding terrain. A forged drop pitman arm corrects steering angles, while polyurethane bump stops limit up-travel and brake line relocation brackets allow the suspension to reach full droop. Heavy-duty replacement radius arms bolt directly into the factory location, built from 1/4" American-made steel and internally gusseted with a lower cam adjustment to dial in front-end caster — a significant upgrade over the factory stamped units.

A heavy-duty replacement transmission crossmember and transfer case indexing ring reposition the front driveline output to correct driveline angles and maintain use of 4WD with factory drivelines. In the rear, 2.5" heavy-duty coil spacers level the stance while retaining factory ride quality without affecting tow capacity. Extended rear sway bar end links, new bump stops, and a track bar bracket are included to compensate for the lift and re-center the rear axle.
