4 Inch Lift Kit w/ Radius Arm | Ford F250/F350 Super Duty (08-10) 4WD | Gas

Built for Super Duty owners who want 4 inches of front lift without sacrificing ride quality — this radius arm kit from BDS Suspension lifts your 2008–2010 Ford F250 or F350 gas truck while preserving steering geometry and supporting up to 35" tires. The radius arm design lets you dial in caster correction across a wide range of lift heights, so your truck handles as good as it looks.

Installed and serviced at Road Runner Wheels & Tires. Most kits go in the same day. Call (678) 400-6467 to schedule.

What you get up front

• Pro-Ride coil springs — gas-engine tuned for smooth, predictable ride across all terrains.
• Tubular radius arms with caster adjustment — replaces factory stamped steel, mounts in OE location, lets you fine-tune geometry for your lift height, and runs OE-style rubber bushings for quiet operation.
• Forged drop pitman arm — minimizes steering angle after the lift to keep your truck tracking straight.
• Track bar drop bracket — heavy-duty forged piece that re-centers the front axle and holds geometry through suspension travel.
• Sway bar relocation — maintains anti-roll stiffness without binding.
• Brake line brackets — keeps lines protected from the suspension.

Out back

The rear uses a high-strength lift block with a u-bolt flip kit for maximum ground clearance. Brake line brackets protect your lines, and you'll choose between leaf springs or block kit — both include your choice of shocks.

Pick your shocks

• BDS NX2 Nitro — comfortable daily driver shocks; best value for street and light off-road use.
• FOX 2.0 Performance Series — tuned for aggressive terrain; nitrogen-charged for consistent damping on rocks and technical trails.

Important notes

• Maximum tire size is 35 x 12.5 — larger tires may contact suspension or body.
• Front lift height is 4 inches; rear is 3 inches when using the block kit, or adjustable 4–5.5 inches with leaf springs.
• Two rear options: block kit without factory overload, block kit with factory overload, or leaf spring setup — confirm which your truck has before ordering.
• Gas engine only — not compatible with diesel powerplants.
