3 Inch Lift Kit w/ Radius Arm | FOX 2.5 Coilover Conversion - Performance Elite | Ford F250/F350 Super Duty (23-26) 4WD

Built for diesel Super Duty owners who want 35-inch tire clearance, better ride quality, and tuning versatility without sacrificing driveline geometry. This 3-inch radius arm lift kit pairs diesel-specific Pro-Ride coil springs with FOX 2.5 Performance Elite coilover shocks — remote-reservoir units tuned for both on-road comfort and rough-terrain capability. You get front caster correction, steering geometry preservation, and the adjustability to dial in your truck exactly how you want it.

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

• Diesel-specific Pro-Ride coil springs — engineered for the extra weight of a diesel engine while maintaining proper ride height and compliance across the range.
• High-strength tubular radius arms with caster adjustment — replace factory stamped steel, mount at factory locations, and let you dial in caster at your chosen lift height. OE-style rubber bushings keep things quiet and maintenance-free.
• 1-3/8" solid steel adjustable track bar — recenter the front axle and lock in proper steering geometry. Pre-assembled with bushings, ready to bolt in.
• Sway bar relocation and brake line brackets — everything needed to keep suspension geometry and braking function correct.
• FOX 2.5 Performance Elite coilover shocks — remote-reservoir design with DSC dual-speed compression adjusters (10 low-speed, 12 high-speed levels) for precision tuning. Black anodized aluminum body sheds heat so you can push hard on rough terrain.

Out back

High-strength fabricated lift block with longer u-bolts — paired with your choice of shock tier. Lifts the rear 1 inch to balance the 3-inch front and maintain proper driveshaft angles.

Pick your shocks

• FOX 2.0 Performance Series — comfortable daily driver shocks with solid tuning right out of the box. No adjustment knobs, no reservoir fiddling — just bolt-on reliability.
• FOX 2.5 Performance Elite — race-proven remote-reservoir technology with DSC adjusters and 10+12 compression levels. Made for owners who want to dial in comfort, handling, and off-road performance on their terms.

Important notes

• Clears up to 35 x 12.5 tires — larger sizes may contact body or suspension components depending on wheel offset and backspacing.
• Radius arm design and adjustable track bar preserve OE driveline geometry and caster angle across the lift range — no driveshaft modification required.
• Fits 2023–2026 Ford F-250 and F-350 Super Duty 4WD (SRW) — both gas and diesel engines. Not compatible with air suspension or factory air springs on certain trim levels — verify your truck's factory options before ordering.
• The diesel-specific Pro-Ride springs are engineered for diesel-equipped trucks. Gas truck kits use different spring rates — do not cross.

Why customers pick this at Road Runner

• Local BDS warranty backing — if anything goes wrong, you walk in, we handle it, no mail-in nonsense.
• Installed by techs who do these every week — we've lifted hundreds of Super Duties; we know the geometry, the tricks, and how to get it right the first time.
• Caster-corrected from day one — radius arms and adjustable track bar mean your steering feel and tire wear stay OE-normal, not wandering or unpredictable.
• Remote-reservoir shock tech keeps you cool on the trail — FOX Elite shocks run longer and harder because they dissipate heat better than traditional monotubes.
• Dual-speed compression tuning — twist the DSC knobs and feel the difference. Soft for smooth highway cruising, stiff for rock crawling — all without tools.
• Your truck lifted this week.
