What you get up front

• Pro-Ride Coil Springs — diesel-specific, full-length springs dialed for smooth ride across varied terrain at this lift height.
• Heavy-Duty Tubular Radius Arms — replace factory stamped steel, mount in stock location, and include caster adjustment for driveline correction. OE-style rubber bushings keep noise and maintenance to zero.
• Forged Drop Pitman Arm & Track Bar Bracket — steering geometry stays true; bracket handles the geometry change that comes with coil spring lift.
• Sway Bar Relocation Kit — maintains suspension compliance without binding.
• Brake Line Brackets — flexes with suspension articulation, no stress on hydraulics.

Out back

High-strength fabricated lift block, longer U-bolts, brake line brackets, and matching rear shocks (your choice of tier) complete the package.

Pick your shocks

• BDS NX2 Nitro Series — comfortable daily driver comfort with nitrogen-charged damping. Included at the kit price.
• FOX 2.0 Performance Series — tuned for smoother highway cruising and light off-road work.
• FOX 2.5 Performance Elite — premium damping and rebound control for serious terrain and max payload cycles.

Important notes

• Transfer Case Re-Indexing Required — At this lift height, the transfer case must be indexed using the supplied precision-built indexing ring (with ARP studs) to clock the transfer case and restore proper front driveline operating angle. A new high-clearance transmission crossmember is included.
• Factory Front Driveshaft Compatible — Re-indexing allows continued use of the factory front driveshaft; no replacement shaft needed.
• Max Tire Size: 38 x 13.5 — Plan tire selection accordingly.
• Fits 2020–2022 Ford F350 Super Duty DRW 4WD Diesel — All cab and bed styles (XL, XLT, Lariat, King Ranch, Platinum); confirmed on diesel powerplants only.
