Zone Offroad D63F 4-Inch Radius Arm Suspension Lift Kit with FOX 2.0 Adventure Series Shocks

The Zone Offroad D63F is a 4-inch radius arm suspension lift kit engineered specifically for 2014–2018 Ram 2500 4WD gas (6.4L Hemi) trucks. This complete lift system replaces the factory radius arms with fully boxed, internally gusseted heavy-duty arms that bolt directly into the factory mounting locations while correcting caster and suspension geometry for improved on-road and off-road performance. The kit delivers 4 inches of front lift via progressive rate coil springs and 2.5 inches of rear lift through rear coil spacers, resulting in a leveled stance with clearance for tires up to 37 inches.

Key Features:

• Heavy-duty replacement radius arms — fully boxed and internally gusseted, designed to bolt into the factory location and correct suspension caster
• Extra-large greaseable bushings at the frame mount to isolate vibrations and extend service life
• Progressive rate front coil springs tuned specifically for the 6.4L Hemi gas engine
• Rear coil spacers providing 2.5 inches of rear lift, mounting directly to the factory axle mount
• Forged drop pitman arm to correct steering angles after lifting
• Heavy-duty fully welded front track bar relocation bracket to re-center the front axle
• Extended polyurethane front bump stops, brake line relocation brackets, and front sway bar relocation hardware
• Rear track bar bracket and extended rear sway bar links to correct rear suspension geometry
• FOX 2.0 Adventure Series IFP gas shocks — nitrogen-charged, twin-tube design with 10-stage velocity-sensitive valving and dual-welded ends for increased strength

All components feature a durable powdercoat finish and are designed for a fully bolt-on installation with no cutting or welding required. The D63F is backed by Zone Offroad's Factory Protection Plus lifetime warranty. Note: Not compatible with factory rear air suspension models. An optional transfer case indexing ring kit is recommended to reduce front driveline angle after installation.
