6 Inch Lift Kit w/ Radius Arm | Ford F250/F350 Super Duty (11-16) 4WD | Diesel

Built for diesel Super Duty owners who want 6 inches of lift without compromising the truck's legendary pulling geometry — this BDS radius arm kit preserves caster and keeps your driveline angles factory-correct. You get front coil springs, radius arms, and your choice of rear blocks (factory 2" or 3") paired with either NX2 Nitro or FOX 2.0 shocks — all engineered to handle the weight and torque of a diesel engine.

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

• BDS radius arm coil spring assembly — replaces the factory track bar with a radius arm for superior geometry correction and caster recovery, keeping your steering response true and reducing bump steer.
• Front coil springs — matched to the lift height and diesel truck weight for a level, controlled ride.

Out back

Rear leaf spring blocks — your choice of factory 2-inch or factory 3-inch blocks to dial in the rear height and stance you want.

Pick your shocks

• BDS NX2 Nitro Series — comfortable daily driver feel with solid damping control and proven reliability; the smart choice for work truck duty.
• FOX 2.0 Performance Series — tuned for rougher terrain and more aggressive off-road use while still handling highway cruising.
