7 Inch Lift Kit w/ Radius Arm | FOX 2.5 Coilover Conversion - Performance Elite | Ford F350 Super Duty DRW (23-26) 4WD | Diesel

Built for diesel Super Duty owners who want 7 inches of height, 38-inch tire clearance, and a dialed-in front end geometry that doesn't compromise driveline angles. This BDS radius arm lift kit pairs diesel-tuned coil springs up front with a rear block lift, transfer case re-indexing to preserve factory driveshaft operation, and your choice of FOX Performance shocks. Engineered for the 2023–2026 F-350 DRW — this is the foundation for a seriously capable rig.

What you get up front

• Pro-Ride diesel coil springs — engineered for the weight and torque of your diesel engine, tuned to lift 7 inches while maintaining caster correction.
• Heavy-duty radius arms — forged steel replacements that preserve front-end geometry and handling under load.
• Forged drop pitman arm and track bar bracket — steering correction hardware that keeps your truck tracking straight at height.
• Sway bar relocation kit — maintains anti-roll geometry and body control.
• Brake line brackets — integrated to prevent hose damage and pinching.

Out back

High-strength fabricated lift block delivers 5 inches of rear height, paired with longer u-bolts and brake line brackets. Keeps the rear proportional and stable — no drooping, no binding.

Pick your shocks

• FOX 2.5 Performance Series HTO — dependable coilover damping for on-road comfort and off-road compliance. Entry point for FOX tuning and adjustability.
• FOX 2.5 Performance Elite — premium internal floating piston design with DSC (Dual Speed Compression) adjusters and external reservoirs. Fine-tune rebound and compression for your exact terrain and load.

Important notes

• Transfer case re-indexing required: This kit includes an indexing ring and new transmission crossmember to allow the factory front driveshaft to operate at the new ride height without angle bind.
• Maximum tire size: 38" × 13.5" — verified clearance at full compression and turning lock.
• Diesel engine tuning: Pro-Ride springs are calibrated for 6.7L diesel weight and torque — do not substitute with gas-truck springs.
• Radius arm geometry: Factory caster and pinion angle correction is engineered into the arm replacement. Do not re-drill or modify mounting points.
• Fitment to trim: Fits King Ranch, Lariat, Limited, XL, and XLT cab and bed configurations.

Why customers pick this at Road Runner

• BDS warranty backed locally: If something fails, you're not shipping to another state — we handle it on-site.
• Transfer case re-indexing done right: Most shops don't understand the geometry. Our techs install these every week and get driveline angles dialed.
• FOX tuning expertise: We help you spec the shock tier that matches your terrain and budget, and we're here if you want to tweak compression or rebound later.
• Diesel-specific parts knowledge: We know the weight, torque, and common pain points of 6.7L builds — no guesswork on spring rate or shock valving.
• Mount and balance available: Most kits are on your truck and road-ready before you leave.
