4.5 Inch Lift Kit | Radius Arm | Diesel | M1 | Ford F-250/F-350 Super Duty (23-26)

Elevate your 23-26 Ford F-250/F-350 Super Duty with Rough Country’s 4.5" Suspension Lift Kit designed specifically for diesel-powered Super Duties. This robust, radius-arm setup not only levels the front and rear for a commanding stance, it also increases ground clearance to tackle tough trails and heavy workloads with confidence. If you want a bold, capable ride that doesn’t compromise handling, this kit is built for you.

Strength and Precision: Tubular Radius Arms

Upgrade from the stock setup with high-clearance tubular radius arms featuring a sturdy 2-inch outer diameter. These arms are engineered for peak strength, durability, and optimized suspension geometry. They bolt directly into factory mounts for a straightforward, secure installation—no drop brackets required. The result is enhanced durability under torque, improved steering feel, and a suspension that stays true to its intended geometry regardless of terrain.

Ride Quality Meets Toughness

The kit preserves ride comfort while delivering a commanding stance. Lifted front coils raise the nose without sacrificing predictable handling, and the package includes sway bar drop brackets and a track bar relocation bracket to maintain proper alignment and steering response across off-road trails and daily driving. Expect smoother transitions from pavement to dirt and steadier highway cruising with less wheel hop and improved axle control.

Durability You Can Feel

Rear traction and load management are reinforced with heavy-duty fabricated blocks that beat standard cast designs for longevity. Anti-axle wrap blocks reduce unwanted movement under heavy torque, helping preserve ride quality and stability when you’re hauling, towing, or pressing through challenging terrain.

Customize Your Ride: Shocks and Tuning

Choose your preferred balance of on-road comfort and off-road performance with configurable shock options. Opt for Rough Country’s nitrogen-charged N3 shocks for a reliable blend of comfortable highway manners and capable trail handling, or upgrade to V2 Monotube shocks for superior heat dissipation and immediate response in demanding off-road conditions. Either choice helps you dial in the exact ride feel you want while maintaining geometry and control.

Effortless, Bolt-On Installation

Designed for a quick, no-hassle install, this kit requires no cutting or drilling. Simply bolt on to restore your truck’s stance and capability, then get back on the road or trail. It also clears up to a 35" tire with proper wheel backspacing, giving you the freedom to achieve your desired look and performance without sacrificing handling.

Why This Lift Stands Out

• Diesel-focused design: Tailored for the torque and chassis behavior of diesel-powered 23-26 F-250/F-350 Super Duty models.
• Radius-arm superiority: 2" OD tubular arms deliver enhanced strength, better geometry, and longer service life compared with stock-style arms.
• Direct bolt-on: Install without drop brackets or complex modifications; keeps factory mounts intact for a cleaner upgrade.
• Managed ride quality: Front coil springs with geo-preserving brackets maintain predictable handling across varied terrain.
• Rear durability: Anti-axle wrap blocks protect the drivetrain under load and torque, preserving ride feel under heavy use.
• Shock versatility: Two high-performance shock options let you tailor the feel to your needs—on-road daily driving versus rugged off-road expeditions.
• Up to 35" tires: Substantial stance expansion without sacrificing steering control or clearance, given proper wheel backspacing.
• Peace of mind: Backed by Rough Country’s Limited Lifetime Warranty for confidence behind every road and trail ascent.

Who Is This For?

Ideal for diesel-equipped 23-26 Ford F-250/F-350 Super Duty owners who want a bold, level look, increased ground clearance, and improved off-road capability without complex modifications. It’s perfect for daily drivers who hit rough dirt roads, overloaded work trucks needing stability under load, or enthusiasts chasing a confident, aggressive stance on trails.

Practical Tips and Insights

• Plan tire upgrades around proper backspacing to maximize tire clearance and maintain steering geometry.
• If you tow or haul often, pair this lift with the N3 shocks for a smoother, more controlled ride under load.
• Regularly inspect radius arms and blocks after off-road sessions to maintain optimal alignment and prevent uneven wear.
