6 Inch Lift Kit w/ Radius Arm | FOX 2.5 Performance Elite Coil-Over Conversion | Ford F250/F350 Super Duty (05-07) 4WD | Diesel

Built for Super Duty diesel owners who want 6 inches of lift without sacrificing ride quality or towing capacity. This BDS kit replaces the factory coil springs with FOX 2.5 Performance Elite coil-overs up front, pairs them with a radius arm for geometry correction, and lets you choose rear lift via leaf springs or block kits—all designed to keep your truck's driveline angles dialed in.

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

• FOX 2.5 Performance Elite coil-overs — fully threaded for ride-height fine-tuning and built to absorb trail abuse without wandering on the highway.
• Radius arm — corrects caster and keeps your front-end geometry true through the lift, so steering stays responsive and tire wear stays even.

Out back

Your choice of rear lift: 6-inch leaf springs deliver the full 6-inch height with factory-matched flex, or select a 4-inch block kit with or without add-a-leaf to dial in your load profile. Overload springs available if you regularly haul heavy fifth-wheel or gooseneck rigs.

Important notes

• Ford F250/F350 Super Duty 4WD diesel engines (2005–2007 model years) only.
• Verify your current wheel offset and tire size before ordering—maximum tire clearance and backspacing requirements apply based on your rear-lift choice.
• Factory driveshaft angle may require inspection post-install to confirm safe operating range.
