7 Inch Lift Kit w/ Radius Arm | FOX 2.5 Performance Elite | Ford F250/F350 Super Duty (23-26) | Diesel

Built for diesel Super Duty owners who want max stance and tire clearance without sacrificing ride quality — this 7-inch radius arm lift kit from BDS pairs Pro-Ride coil springs up front with your choice of rear blocks or leaf springs, clearing up to 38" tires while preserving driveline geometry through factory driveshaft retention and transfer case re-indexing.

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-specific coil springs — engineered for Super Duty weight and payload, delivering a planted ride at 7 inches of lift.
• Heavy-duty replacement radius arms — maintain steering geometry and articulation under load.
• Forged drop pitman arm and track bar bracket — correct caster and keep your steering box centered.
• Sway bar relocation kit — preserves anti-roll stiffness at the new ride height.
• Brake line brackets — route and secure lines safely away from moving components.

Out back

Choose between a high-strength fabricated lift block (for 4.5" or 6" of rear lift depending on configuration) or a leaf spring upgrade — both come with longer u-bolts, brake line brackets, and matched shocks to keep your rear end stable and level.

Pick your shocks

• FOX 2.5 Performance Series HTO — proven street-and-trail damping tuned for Super Duty diesel platforms.
• FOX 2.5 Performance Elite — premium remote-reservoir shocks with external fluid and heat dissipation for extreme duty and consistent response.

Important notes

• Transfer case indexing ring and new transmission crossmember included — required to use the factory front driveshaft at this lift height.
• Maximum tire size: 38" x 13.5" with OE or OE-equivalent wheels.
• Fits 2023–2026 F-250 and F-350 Super Duty diesel trucks, both SRW and DRW configurations.
• Rear lift height varies: 4.5" with blocks (single-year tuning), 6" with leaf springs for multi-year consistency.
