7 Inch Lift Kit w/ 4-Link | Ford F250/F350 Super Duty (20-22) 4WD | Diesel

Built for diesel F-250 and F-350 owners who want 7 inches of lift without sacrificing driveline geometry, this 4-Link kit from BDS combines a purpose-built coil-spring front end with rear blocks and transfer-case indexing to keep your factory driveshaft working right. You get up to 38" of tire clearance, caster correction through the full suspension arc, and a ride tuned for the weight of a diesel engine.

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-rated, full-length springs engineered for the weight and torque of a Super Duty powerplant.
• 4-Link Control Arm Conversion — replaces factory stamped-steel radius arms with high-strength ¼-inch steel brackets and HD control arms to correct axle positioning and preserve caster geometry throughout wheel travel.
• Forged Drop Pitman Arm & Track Bar Bracket — maintains steering response and Ackermann geometry at this lift height.
• Sway Bar Relocation — repositioned for proper suspension clearance and continued anti-roll performance.
• Brake Line Brackets — custom routing to protect lines and maintain factory brake function.

Out back

The rear uses a high-strength fabricated lift block paired with longer u-bolts, brake line brackets, and a matching set of shocks. At 6 inches of rear lift, the block sits stable and predictable under load.

Pick your shocks

• NX2 Nitro Series — comfort-tuned nitrogen monotube shocks that handle daily driving and light trail work without breaking the bank.
• FOX 2.0 Performance Series — tuned internally for mid-range off-road duty; firmer than Nitro, more compliant than FOX Elite.
• FOX 2.5 Performance Elite — premium internal bypass dampers with external DSC adjusters for compression and rebound tuning on the fly.

Important notes

• Transfer-case indexing ring with ARP studs is included and required at this lift height to clock the transfer case and optimize front driveline angle. A high-clearance transmission crossmember is supplied.
• Factory front driveshaft is reused after indexing; no driveshaft replacement needed.
• This kit is designed for 2020–2022 Ford F-250 and F-350 Super Duty 4WD diesel trucks and is compatible with XL, XLT, Lariat, King Ranch, and Platinum trim levels.
• Maximum tire size is 38 x 13.5 inches.
