Built to Perform on Every Terrain

If you're ready to give your 1999–2004 F250 or F350 4WD the ride height it deserves without compromising on quality or comfort, the Zone Offroad 4 inch Lift Kit with FOX 2.0 Shocks and radius U-bolts is a great solution. Designed to deliver a smooth, capable ride both on and off the pavement, this kit clears up to 35 inch tires while giving your truck a bold, leveled stance that looks right at home on the road or in the dirt. Up front, new leaf springs with tapered leaves, OE-style rubber bushings, and anti-friction pads ensure long-term performance with better ride quality than typical aftermarket setups. The heavy-duty track bar keeps the front axle properly centered, which translates to tighter handling and improved control during suspension movement. Out back, a 3 inch block and U-bolt setup brings the rear up to match, and the radius-style U-bolts are tailored for trucks using factory-style radius top plates, ideal for most 2001–2004 models.

Serious Shock Performance That Doesn’t Ride Like a Brick

What truly sets this kit apart is the inclusion of FOX 2.0 Adventure Series shocks. These are far from entry-level dampers, they're built with a steel monotube body, a high-flow piston, and an internal floating piston (IFP) that maintains consistent damping under pressure. Whether you’re crawling through trails, hauling gear, or cruising down the highway, the FOX 2.0s respond better to changing terrain and help smooth out the ride without sacrificing control. Compared to standard twin-tube options, they hold up better under heat and stress, making them ideal for trucks that see real use. The kit is designed to bolt into factory locations and comes complete with hardware for a clean, reliable install. From the precision fitment to the thoughtful inclusion of radius U-bolts, every detail of this system has been engineered to ensure your Super Duty rides as good as it looks.
