4 Inch Lift Kit w/ Radius Arm | Ford F250/F350 Super Duty (05-07) 4WD | Gas

Built for Super Duty owners who want a truck that sits higher, hauls harder, and turns sharper — this 4-inch radius arm lift kit transforms your 2005–2007 F250 or F350 gas engine into a capable work rig with room for 35" tires. BDS engineered it to preserve steering geometry and driveline angles, so your truck feels planted whether you're towing or tackling rough terrain.

What you get up front

• Pro-Ride gas-specific coil springs — full-length springs tuned for weight and ride quality on gasoline F250/F350 trucks, delivering smooth, predictable performance across varied terrain.
• Tubular radius arms with caster adjustment — heavy-duty replacements for factory stamped steel, mounted in the factory location with OE-style rubber bushings for quiet, service-free operation and adjustable caster to dial in geometry across lift heights.
• Forged drop pitman arm and track bar bracket — steering correction hardware that minimizes steering angle and keeps the front axle recentered through suspension travel.
• Sway bar relocation, brake line brackets, and choice of shocks — complete bolt-on package ready to hit the road.

Out back

The rear uses a high-strength lift block, u-bolt flip kit for maximum ground clearance, brake line brackets, and your choice of shock tiers. Optional leaf spring setup available for customers who prefer that geometry.

Pick your shocks

• BDS NX2 Nitro — comfortable daily driver shocks with nitrogen charging for consistent performance and easy maintenance.
• FOX 2.0 Performance Series — premium ride quality with faster response and tuning for serious off-road use.

Important notes

• Kit supports up to 35" tires — larger sizes may require trimming or additional clearance work.
• Caster adjustment built into radius arms — allows tuning across different lift heights, but fitment varies by trim level and factory options.
• Rear block lift combined with u-bolt flip maximizes ground clearance; leaf spring option available as alternative rear geometry.
• Gas-engine application only — not compatible with diesel or 6.0L powerplants.
