ReadyLIFT 3.5" SST Lift Kit | 2023–2026 Ford F-250/F-350 Super Duty 4WD

Is This for You?
You're running a 2023–2026 Ford F-250 or F-350 Super Duty and you need a lift kit that was engineered from the ground up for this generation's radius arm front suspension — not adapted from an older platform. You want 37" tires, proper axle geometry, and OEM ride quality preserved on both the highway and the trail. The ReadyLIFT 69-23350 is the first-to-market radius arm drop bracket kit for the new Super Duty, delivering 3.5" of front lift and 4" of rear block height with every geometry correction component included and zero frame cutting required.

The Result
Three and a half inches of front lift via heavy-duty coil spring spacers with poly sound isolators, paired with all-new radius arm drop brackets that maintain proper axle geometry at the new ride height — a critical correction that generic spacer kits omit entirely. Sway bar drop brackets, bump stop extensions, front shock extension brackets, extended-length front brake line brackets, and an OEM-style track bar relocation bracket complete the front geometry package. The rear is lifted with 4" OEM-style cast blocks featuring integrated bump stop landings and new longer U-bolts. The result is a Super Duty that runs a 37x12.5" tire on a 17"+ x 9" wide +18 offset wheel with only minor front valance trimming — no cutting of OEM parts, no welding, no compromises.

Verified Fitment (OFAS Standard)
✅ Fits: 2023–2026 Ford F-250 Super Duty 4WD (SRW)
✅ Fits: 2023–2026 Ford F-350 Super Duty 4WD (SRW)
❌ Does NOT fit: Dually (DRW) applications
❌ Does NOT fit: Trucks equipped with overload springs — overload-length U-bolts must be sourced separately
❌ Does NOT fit: Tremor models — see ReadyLIFT 69-23250 or 69-23251 for Tremor applications
❌ Note: 2023–2026 trucks equipped with the Onboard Scale option require the Auto-Leveling Headlight Bracket (PN: 67-23410) — sold separately

Wheel & Tire Fitment
Recommended tire size: 37x12.5". Recommended wheel: 17" and up x 9" wide, +18 offset / 6" backspacing. Minor trimming of the front valance may be necessary depending on tire tread design and true diameter. ReadyLIFT wheel and tire fitment recommendations are based on Wheel Pros wheels and Nitto tires. Actual dimensions vary meaningfully by manufacturer — overall diameter, tread width, aspect ratio, and sidewall construction will differ. Every tire and wheel combination must be test fit prior to final installation. Upgrading to heavier 10-ply (Load Range E) all-terrain or mud-terrain tires will noticeably increase suspension stiffness and alter ride harshness compared to factory 6-ply (Load Range C) tires. Consult your local installer for application-specific guidance.

Installation & Engineering Notes
This is a complete bolt-on system — no cutting of OEM parts and no welding required. Radius arm drop brackets must be installed to maintain proper axle geometry — do not omit. A professional 4-wheel alignment is mandatory post-installation to verify torque specs, confirm ride height, and lock in corrected geometry. Trucks equipped with overload springs will require separately sourced overload-length U-bolts. Trucks with the Onboard Scale option require the separately sold Auto-Leveling Headlight Bracket (PN: 67-23410). Lifting your vehicle raises its center of gravity; exercise appropriate caution on- and off-road. All Advanced Driver Assistance Systems (ADAS) including Ford Co-Pilot360, Pre-Collision Assist, Lane-Keeping System, BLIS, and automatic headlight leveling must be checked and recalibrated after installation.

Engineering Question: Is your 2023–2026 Super Duty a SRW or DRW configuration, does it have overload springs, and is it equipped with the Onboard Scale or Tremor package? Confirm all options before ordering — dually, Tremor, and overload spring applications have specific compatibility requirements not covered by the base 69-23350 kit.
