5 Inch Lift Kit w/ Radius Arm | Ford F250/F350 Super Duty (20-22) 4WD | Diesel

Built for diesel Super Duty owners who need 5 inches of front lift without sacrificing ride quality or steering geometry — this radius arm kit from BDS Suspension is engineered to clear up to 37" tires while keeping your truck planted and predictable. The diesel-specific coil springs, caster-corrected radius arms, and steering geometry brackets make this the go-to choice for 2020–22 F-250 and F-350 trucks running heavy loads or aggressive terrain.

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

• Pro-Ride Coil Springs — diesel-specific, full-length springs tuned for 5" of lift with a smooth, predictable ride across pavement and rough terrain.
• HD Tubular Radius Arms — heavy-duty drop-in replacements with caster correction and OE-style rubber bushings for quiet, service-free operation across a wide range of lift heights.
• Drop Pitman Arm & Track Bar Bracket — forged steering components that recenter the axle and maintain geometry through suspension travel, so your truck drives true at height.
• Sway Bar Relocation & Brake Line Brackets — everything needed to integrate the new ride height without kinks or rubbing.

Out back

A high-strength fabricated lift block, longer u-bolts, and brake line brackets deliver 4–5" of rear lift to match your front. You'll pair this with your choice of shock tier below.

Pick your shocks

• BDS NX2 Nitro Series — a matched pair front and rear for a consistent, comfortable daily-driving feel at a great value.
• FOX 2.0 Performance Series — tuned for light off-road duty and highway cruising; adds adjustable ride-height control for fine-tuning your truck's stance.
• FOX 2.5 Performance Elite — the premium choice with reservoir damping, fully adjustable compression and rebound, and proven durability in extreme terrain and towing scenarios.

Important notes

• Max tire clearance is 37 x 12.5 inches. Larger tires may require trimming or cause rubbing.
• Front lift is achieved via coil spring; rear lift uses a block system — both methods preserve factory driveline geometry and suspension angles.
• OE steering and suspension components (pitman arm, track bar, radius arms) are replaced as part of the kit to maintain OE steering effort and response.
• This kit is designed for 2020–2022 Ford F-250 and F-350 Super Duty diesel 4WD trucks in all trim levels (XL, XLT, Lariat, King Ranch, Platinum).
