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

Built for diesel Super Duty owners who want level stance, better geometry, and room for 35-inch rubber — this 3-inch radius arm lift kit from BDS Suspension raises your 23–26 Ford F-250 or F-350 Super Duty 3 inches up front and 1 inch out back while keeping driveline angles correct. You get Pro-Ride diesel coil springs, heavy-duty tubular radius arms with caster correction, a solid steel track bar for steering recenter, and your choice of shocks — everything bolts to factory mounting points.

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 Coil Springs — purpose-built for the weight and torque of the 6.7L diesel, tuned to deliver smooth, predictable ride across highway and rough terrain without sagging under load.
• HD Tubular Radius Arms — replace soft factory stamped steel with high-strength tube arms that allow caster adjustment across lift heights and keep suspension geometry stable through the arc of travel.
• 1-3/8" Solid Steel Adjustable Track Bar — recenter the front axle at your new lift height to preserve steering feel and handling, pre-assembled with bushings and ready to bolt in.
• Sway Bar Relocation & Brake Line Brackets — factory geometry preservation hardware so nothing binds or rubs as the truck articulates.

Out back

A high-strength fabricated lift block raises the rear 1 inch, paired with longer u-bolts and your choice of matching NX2 Nitro or FOX Performance shocks to control the added height and keep the rear planted under payload.

Pick your shocks

• BDS NX2 Nitro Series — comfortable daily-driver damping with nitrogen charge for consistent control and durability at the best price point.
• FOX 2.0 Performance Series — step up to faster-reacting dampening, improved small-bump compliance, and mid-range tunability for owners who want sharper feel without premium cost.
• FOX 2.0 Performance Elite — top tier with FOX's proven remote-reservoir design, external adjusters, and elite valving for serious off-road and high-speed highway capability.

Important notes

• Maximum tire size is 35 × 12.5 inches — larger rubber will contact frame or suspension components.
• Factory air suspension, RamBox, and some option packages may have fitment conflicts — verify your configuration before ordering.
• Diesel powerplant model years 2023–2026, 4WD SRW (Single Rear Wheel) only — will not fit DRW trucks or gasoline engines without engineering review.
