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

Built for diesel F-250 and F-350 owners who want 3 inches of front lift, level stance, and room for 35-inch tires without sacrificing ride quality. This BDS Suspension radius arm kit delivers the lift height you want while preserving factory driveline geometry through diesel-tuned coil springs, caster-corrected radius arms, and a track bar engineered to keep steering tight at any lift height.

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 Diesel Coil Springs — full-length, load-rated coil springs engineered specifically for diesel weight and designed to deliver a smooth, predictable ride across pavement and rough terrain.
• HD Tubular Radius Arms — factory-location mounting with caster adjustment lets you dial in geometry across the full range of lift heights, plus OE-style rubber bushings for quiet, service-free operation.
• Adjustable Track Bar — 1-3/8-inch solid steel construction with pre-assembled bushings; recenter your front axle at any lift height to maintain precise steering and handling.
• Sway Bar Relocation & Brake Line Brackets — everything needed to integrate the lift into your truck's existing brake and suspension geometry.

Out back

High-strength fabricated lift block pairs with longer u-bolts to raise the rear 1 to 1.5 inches, leveling your truck's stance. Your choice of shock tier matches the front for a balanced, tuned suspension system.

Pick your shocks

• NX2 Nitro Series — comfortable daily driver shocks with nitrogen charge for consistent damping and responsive handling on street and light off-road use.
• FOX 2.0 Performance Series — tuned for trucks that see a mix of highway and moderate off-road, with FOX's proven velocity-sensitive piston technology.
• FOX 2.5 Performance Elite — premium reservoir design and position-sensitive damping for maximum control on aggressive terrain and high-speed driving.

Important notes
