Zone Offroad F33F Radius Arm Suspension Lift Kit with Fox Adventure Series Shocks - 6-Inch 2.0

The Zone Offroad F33F is a complete 6-inch radius arm suspension lift system engineered for the 4WD gas-powered Ford F-250 and F-350 Super Duty. This kit delivers a commanding stance with the clearance needed to run up to 37-inch tires, transforming your Super Duty into a capable off-road machine without sacrificing everyday drivability.

Paired with FOX 2.0 Adventure Series shocks, this kit provides a smooth, controlled ride on-road and confident damping performance off-road. The monotube shock design uses an internal floating piston (IFP) to separate shock oil from the high-pressure nitrogen charge, ensuring consistent performance under demanding conditions.

Key Features:

• High-strength 1/4" steel radius arms correct caster angle, improve tire clearance, and maximize ground clearance
• Heavy-duty radius arms improve overall strength and provide additional tire clearance over drop-style radius arm kits
• Front coil springs deliver the 6-inch lift height up front with improved ride quality
• Rear lift block with overload levels the stance and supports heavier loads
• Dual rear Add-A-Leaf kit provides additional rear lift and improves payload capacity
• Bump stop extensions properly limit suspension up-travel to protect the vehicle
• Brake line relocation brackets allow reuse of factory brake lines
• Longer U-bolts included for a complete rear installation
• Steering components included to maintain factory-consistent handling geometry

Like all Zone Offroad lift systems, the F33F is made in the USA and backed by Zone's Shield Lifetime Warranty along with their Factory Protection Plus program, which includes a 5-year/60,000-mile drivetrain warranty for added peace of mind. Professional installation by a certified mechanic is strongly recommended.
