9 Inch (Gas) | 8 Inch (Diesel) Lift Kit w/ 4-Link | Ford F250/F350 Super Duty (20-22) 4WD

Built for Super Duty owners who want maximum clearance and a commanding stance without sacrificing driveline geometry. This 9-inch (gas) / 8-inch (diesel) 4-Link lift kit from BDS combines coil-spring front lift with full-replacement leaf springs out back, holding up to 40" tires while the 4-Link conversion corrects axle geometry for stable handling at 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 coil springs — gas-specific, full-length springs engineered for consistent lift height and smooth ride on- and off-road.
• 4-Link control arm conversion — high-strength 1/4-inch steel brackets and HD upper/lower control arms correct axle positioning and minimize caster change, delivering predictable handling at this height.
• Forged drop pitman arm & track bar bracket — factory steering geometry is preserved through precision bracket work.
• Sway bar relocation & bump stop extensions — clears suspension travel and maintains handling feel.
• Stainless steel braided brake lines — accommodate suspension movement without flex or failure.
• NX2 steering stabilizer — reduces bump-steer and on-center drift at height.
• Transfer case indexing ring & transmission crossmember — allows the factory front driveshaft to operate safely; ARP-studs ensure durability.

Out back

Full-replacement Glideride leaf springs deliver the complete 8" rear lift with factory-grade load capacity. Built-in overload spring, u-bolts, and brake line brackets are all included. Your choice of shock pairs the rear to your driving style — see below.

Pick your shocks

• BDS NX2 Nitro Series — everyday comfort and control; nitrogen-charged for consistent damping on pavement and light off-road. $3,970.55
• FOX 2.0 Performance Series — track-tuned damping and faster response; premium choice for those who push harder terrain and want the edge. $4,570.55

Important notes

• This kit is engineered for 2020–2022 Ford F-250 and F-350 Super Duty 4WD models (gas and diesel variants differ in lift height — confirm your engine type before ordering).
• Maximum tire size is 40 x 13.5 inches. Backspacing and offset must accommodate this clearance; RRW can advise on compatible wheel choices at time of sale.
• Transfer case indexing and new transmission crossmember are required at this height to maintain factory driveshaft angles. Both are supplied in the kit.
• The 4-Link conversion corrects caster geometry; no additional modifications are needed to steering or suspension geometry.
• Compatible with XL, XLT, Lariat, Platinum, and King Ranch trim levels.
