Zone Offroad D67F 5.5-Inch Radius Arm Suspension Lift Kit with Fox 2.0 Adventure Series Shocks

The Zone Offroad D67F is a complete 5.5-inch radius arm suspension lift kit engineered specifically for 2013–2018 Ram 3500 4WD gas-powered trucks. Designed to dramatically improve ground clearance, off-road capability, and overall stance, this kit includes every component needed for a thorough front and rear lift — from progressive rate front coil springs to rear lift blocks — while preserving safe, predictable on- and off-road handling.

Key Features:

• 5.5-inch front lift via high-strength progressive rate coil springs tuned for the weight of the 6.4L Hemi gas engine
• Heavy-duty radius arm drop brackets correct caster angle and restore proper suspension geometry after lifting
• Forged drop pitman arm and track bar relocation bracket correct steering angles and re-center the front axle
• Extended front bump stops, sway bar relocation hardware, and brake line relocation brackets maintain factory-like operating angles
• Rear lift blocks and U-bolts level the stance front to rear
• Fox 2.0 Adventure Series shocks at all four corners — featuring powdercoated steel bodies and internal floating piston (IFP) technology for fade-free performance on and off pavement
• Clearance for up to 37-inch tires
• 100% bolt-on design — no cutting or welding required

The included Fox 2.0 Adventure Series shocks are nitrogen-charged with a twin-tube design and 10-stage velocity-sensitive valving, delivering confident control on the trail and a comfortable ride on the highway. All hardware is powdercoated for long-term corrosion resistance.

Important Notes: Fits 6.4L gas-equipped Ram 3500 4WD trucks only. Not compatible with factory rear air-ride suspension. Front driveline vibration may occur at speeds over 35 mph in 4WD — an optional transfer case indexing ring kit is available to address this. Vehicles with a two-piece driveshaft and carrier bearing may require an optional carrier bearing drop kit.
