7 Inch Lift Kit w/ Radius Arm | Ford F250/F350 Super Duty (23-26) 4WD | Diesel

Built for diesel Super Duty owners who want 7 inches of commanding lift without sacrificing driveline geometry — this BDS radius arm kit delivers the stance, clearance for up to 38" tires, and corrected steering geometry your F250 or F350 4WD needs. Every component is engineered to work together, preserving OE performance while opening up serious off-road and towing capability.

What you get up front

• Pro-Ride diesel-specific coil springs — custom-valved for the weight and response of a diesel engine, maintaining ride quality under load.
• Heavy-duty replacement radius arms — engineered to handle the torque and geometry demands of a 7-inch lift while keeping your steering geometry true.
• Forged drop pitman arm and track bar bracket — restores OE steering feel and caster angle so your truck drives straight and responsive.
• Sway bar relocation kit — keeps anti-roll stiffness working as intended at the new ride height.
• Brake line brackets — repositioned to prevent kinking or rubbing at full articulation.

Transfer case and driveshaft

At 7 inches, your transfer case needs re-indexing to allow the factory front driveshaft to work without binding. BDS supplies the indexing ring and a new transmission crossmember — that's the detail that separates a proper install from a cut-and-hope situation.

Out back

The rear uses a high-strength fabricated lift block, longer u-bolts sized for the new geometry, and brake line brackets to keep everything routed safely. Matched shock choice below.

Pick your shocks

• BDS NX2 Nitro Series — comfortable daily driver with excellent bump compliance; the best value for work trucks and mixed duty.
• FOX 2.0 Performance Series — tuned for faster rebound and sharper handling; ideal if you're towing heavy or running rough terrain regularly.
• FOX 2.5 Performance Series HTO — high-temperature operation and firmer valving for sustained towing and aggressive rock crawling.
• FOX 2.5 Performance Elite — top-tier external reservoir, dual-speed compression, and ride-height-adjustable damping for maximum control on any surface.

Important notes

• Maximum tire clearance is 38 inches — stay within that limit to avoid suspension contact or binding.
• Transfer case re-indexing is required; BDS provides the indexing ring and new transmission crossmember.
• This kit is designed for 2023–2026 F250 and F350 Super Duty 4WD diesels; verify your specific model year and drivetrain configuration before ordering.
• Factory driveshaft compatibility is preserved after re-indexing — do not attempt to use aftermarket shafts unless explicitly recommended.
