8 Inch Lift Kit | 4-Link Conversion | Ford F250/F350 Super Duty (11-16) 4WD | Diesel

This BDS 4-link conversion kit replaces the factory radius arms with a solid 4-link setup that handles real off-road abuse. You get corrected caster geometry, increased suspension travel, and room for up to 37-inch tires — all while preserving the driveline angles that keep your diesel running smooth.

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

• 4-Link Conversion Arms — replaces the OE radius-arm design with a factory-proven triangulated geometry that resists bind and handles payload without walk-out.
• Front Coil Springs — matched to the 8-inch lift and your truck's weight, pre-sized for diesel models.
• Front Sway Bar Links — extended to suit the new suspension arc.
• Bump Stops — valved to prevent bottoming under full compression.
• Hardware & Brackets — all fasteners, mounts, and relocation brackets included.

Out back

Rear uses factory-location add-a-leaf springs stacked with the OE pack to lift the bed 8 inches in line with the front. Shackle relocation and extended U-bolts keep geometry clean.

Pick your shocks

• BDS NX2 Nitro Series — comfortable daily driver with smooth damping. Fits on-road and light trail use. Starting at $3,434.55.
• FOX 2.0 Performance Series — premium internal floating piston design with speed-sensitive adjusters. Built for aggressive terrain and high-speed desert work. $4,034.55.

Important notes

• OE wheels must clear the new coil buckets — BDS recommends a minimum backspacing of 4.5 inches and offset no less than +12 mm.
• Maximum tire size is 37 inches. Running larger will rub at full droop and compromise suspension articulation.
• Vehicles equipped with factory air suspension or integrated RamBox are not compatible with this kit.
• Driveshaft angles are corrected by the 4-link geometry — no re-indexing required.
• ABS and stability control systems function normally; no recalibration needed.

Why customers pick this at Road Runner

• Installed by diesel suspension specialists who bolt these kits every week — you get it right the first time.
• BDS warranty is honored on-site — no back-and-forth with the manufacturer.
• Real caster correction means no death wobble, no tire wear surprises.
• We stock both shock tiers so you can upgrade later without a second visit.
