6 Inch Lift Kit | 4-link | No Ovld | D/s | V2 | Ford F-250/f-350 Super Duty (17-22)

Built for Super Duty diesel owners who want a 6-inch lift with corrected geometry and proven 4-link control-arm durability, this Rough Country lift kit replaces your factory coil springs and blocks with a fully adjustable 4-link front suspension, rear fabricated blocks, and a matched pair of V2 Monotube shocks. You'll gain the ground clearance and travel for 35–37-inch tires while maintaining proper caster geometry for factory-like handling on and off the pavement.

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

What's included

• Box Kit — Structural frame component for Ford Super Duty (17–22) that anchors the lift assembly.
• 4.5–6 inch Up Arm Kit — Upper control arms engineered for the full range of lift travel while maintaining suspension geometry.
• 4.5–6 inch Lower Arms — Adjustable lower control arms that allow fine-tuning of caster angle post-install.
• Radius Arm Drop Brackets — Position the radius arms to preserve proper caster and prevent bump-steer and torque effects.
• 4.5-inch Fabricated Anti-Wrap Blocks — Stronger than cast blocks; the anti-wrap design prevents axle binding and maintains stock ride quality under load.
• CV Front Driveshaft — Diesel-rated CV driveshaft for 4WD Super Duty, re-indexed to maintain driveline angles after the 6-inch lift.
• 6-inch Coil Springs — Lifted coil springs that work with the block kit to achieve the full 6 inches of front height.
• V2 Monotube Shock Absorbers (Front & Rear Pair) — Nitrogen-charged shocks tuned for balanced on-road comfort and off-road control, valved specifically for this application.
• Extended Stainless Steel Brake Lines & Brackets — Prevent brake-line stretch and ensure proper hose clearance as the suspension travels.

Important notes

• This kit is engineered for diesel Super Duty 4WD models only — does NOT fit gas-engine variants.
• Not compatible with automatic transfer case — requires manual-shift transfer case.
• Does NOT fit dually models (dual-rear-wheel configurations).
• Not compatible with Tremor Factory Trim Package — verify your truck's option codes before ordering.
• The fabricated lift block replaces the factory block entirely — no stacking or modification of OE hardware.
• Proper caster alignment is critical to preserve handling and prevent premature tire wear — performed in-house by our technicians as part of the install.

Why customers pick this at Road Runner

• Geometry done right — Radius arm drop brackets and adjustable lower control arms allow our techs to dial in exact caster and ride quality, not just bolt and drive.
• Lifetime Rough Country warranty backed locally — any defect in materials or workmanship covered for the life of the vehicle, honored right here.
• Diesel-specific engineering — Factory-matched CV driveshaft, brake-line drops, and shock valving account for the weight and torque curve of 6.7L and 7.3L engines.
• Professional alignment included — Caster, camber, and toe corrected in-house on every lift install so you drive home with factory-spec geometry.
• Same-day installs — Our team performs Super Duty lifts every week; we know the hardware, tool needs, and no-surprises approach that keeps your truck off the lift bay in one shift.
