9 Inch Lift Kit w/ 4-Link | FOX 2.5 Performance Elite Coil-Over Conversion | Ford F250/F350 Super Duty (20-22) 4WD | Diesel

Built for diesel F250/F350 owners who want serious height and capability without sacrificing driveline geometry, this 9-inch 4-Link lift kit pairs a FOX 2.5 Performance Elite coil-over front end with BDS Glideride leaf springs out back. You get up to 38-inch tire clearance, factory driveshaft compatibility through transfer-case indexing, and the geometry correction that keeps your truck handling sharp at any height.

What you get up front

• FOX 2.5 Performance Elite coil-over shocks — Diesel-tuned remote-reservoir design with DSC dual-speed compression adjusters (10 low-speed, 12 high-speed levels). Keeps temps down when you're pushing hard, settles smooth on pavement.
• 4-Link control arm conversion — Replaces factory radius arms with high-strength 1/4-inch steel brackets and HD upper/lower control arms. Corrects caster angle and eliminates geometry sag across the full range of suspension travel.
• Forged drop pitman arm & track bar bracket — Steering geometry stays true; sway bar relocates for clearance.
• Brake line brackets & transfer-case indexing ring — Precision ARP-stud indexing ring clocks your transfer case so the factory front driveshaft works without binding. New high-clearance transmission crossmember included.

Out back

Full-replacement BDS Glideride leaf springs with new u-bolts, brake line brackets, and a matching pair of FOX Performance shocks keep the rear planted and compliant whether you're loaded or light.

Important notes

• Max tire size: 38 × 15.5 inches.
• Transfer-case indexing and new transmission crossmember are required at this lift height to preserve factory front driveshaft angles and function.
• 4-Link conversion corrects caster throughout wheel travel — no secondary drop brackets needed.
• Kit is diesel-specific for 2020–2022 F250/F350 Super Duty 4WD models.
