5 Inch Lift Kit w/ Radius Arm | Ford F250/F350 Super Duty (23-26) 4WD | Diesel

Built for diesel Super Duty owners who need 5 inches of lift without compromising ride quality or steering geometry. This radius arm kit delivers the stance and tire clearance you want — up to 37" — while preserving factory driveline angles and keeping your truck planted on rough terrain. Pro-Ride coil springs tuned for diesel weight, adjustable caster correction, and a full complement of steering-geometry brackets mean your F250 or F350 handles like it was engineered this way from the factory.

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

• HD Radius Arms — Tubular construction replaces factory stamped steel, with factory-location mounts and built-in caster adjustment. OE-style rubber bushings at the frame keep NVH down.
• Pro-Ride Coil Springs — Full-length, diesel-specific springs tuned for your truck's weight and engineered to deliver predictable ride across pavement and rough terrain alike.
• Steering Correction Package — Forged drop pitman arm and heavy-duty track bar drop bracket re-center the axle and keep steering geometry in phase through suspension travel.
• Sway Bar Relocation & Brake Line Brackets — Everything needed to integrate the lift without binding or chafing factory lines.

Out back

High-strength fabricated lift block, longer u-bolts, and brake line brackets support your rear axle at the new height. Paired with your choice of shock tier for the ride character you want — comfort-first daily driving or performance tuning for rock crawl.

Pick your shocks

• BDS NX2 Nitro Series — Comfortable, dependable nitrogen-charged damping for daily driving and moderate off-road work. The value choice.
• FOX 2.0 Performance Series — Firmer, tuned for heavier loads and more spirited trail use. Better body control than Nitro.
• FOX 2.5 Performance Elite — True dual-speed compression and rebound tuning. Premium valving for the harshest terrain and sustained performance.

Important notes

• Two base configurations: Block Kit (with or without factory overload spring provision) or full Leaf Spring replacement. Choose based on your current rear setup and payload needs.
• Clears up to 37" tires; verify backspacing and offset with our team to avoid rubbing.
• Diesel-specific geometry tuning preserves driveshaft angles and front-end steering behavior across the full 5-inch lift range.
