5 Inch Lift Kit w/ Radius Arm | FOX 2.5 Performance Elite Coil-Over Conversion | Ford F250/F350 Super Duty (20-22) 4WD | Diesel

Built for diesel truck owners who demand 5 inches of lift without sacrificing on-road manners or off-road capability — this radius arm kit pairs heavy-duty tubular geometry with FOX 2.5 Performance Elite coil-overs to handle 37-inch tires while preserving factory steering geometry and caster correction. It's the setup serious Super Duty drivers choose when they want it all: stance, clearance, and drivability.

What you get up front

• FOX 2.5 Performance Elite Coil-Over Shocks — Diesel-tuned remote-reservoir units with DSC dual-speed compression adjusters (10 low-speed, 12 high-speed levels) for precise on-road comfort and off-road control.
• Heavy-Duty Tubular Radius Arms — Replace factory stamped steel with high-strength tube arms that retain caster adjustment capability and factory-style rubber bushings for quiet, service-free operation.
• Forged Drop Pitman Arm & Track Bar Drop Bracket — Steering geometry correction kit that minimizes steering angle and keeps axle geometry in phase through suspension travel.
• Sway Bar Relocation Hardware — Maintains suspension geometry and handling balance at full lift height.
• Brake Line Brackets — Protects hydraulic lines throughout suspension articulation.

Out back

The 3-inch rear raise uses a high-strength fabricated lift block paired with longer u-bolts and matching FOX Performance shocks. This pairing keeps the rear in harmony with the front 5-inch lift while maintaining geometry stability and ride quality.

Pick your shocks

• FOX 2.0 Performance Series — Rock-solid daily-driver shocks with proven durability. No DSC adjusters — set once and forget. Ideal if you want the lift geometry without tuning complexity.
• FOX 2.5 Performance Elite — Remote reservoir, DSC dual-speed compression adjusters, and race-proven internals. The choice for owners who want to dial in comfort on pavement and confidence in rough terrain.

Important notes

• Maximum tire clearance: 37 × 12.5 inches. Larger tires may contact suspension or body components.
• Fits 2020–2022 Ford F-250 and F-350 Super Duty 4WD diesel models only (gas variants require different geometry).
• Factory stamped radius arms must be removed and replaced; BDS tubular arms are supplied with all necessary hardware for bolt-in installation at factory mounting points.
• Caster-corrected radius arms and drop pitman arm preserve OE steering feel and axle tracking through full suspension travel.
• Longer rear u-bolts are included; factory fasteners are not reused.

Why customers pick this at Road Runner

• Caster correction is baked in via the radius arm design and drop pitman arm — geometry stays true from day one.
• FOX shocks arrive tuned and ready; our techs can dial in DSC adjusters to match your driving style before you leave.
• 5-year BDS warranty backed locally — if anything goes wrong, you walk in, we handle it.
• Diesel-specific tuning throughout — we don't guess at weight and torque, we build for what your truck actually does.
