Make Your Super Duty Stand Taller And Ride Better

If your truck looks like it's always leaning forward, it's time to level the playing field, and the stance. The Rancho RS66553B 2.5-Inch Radius Arm Leveling Kit is designed to bring the front of your 2011–2018 Ford F250 or F350 4WD up to match the rear, giving your Super Duty a stronger, more confident look. Beyond appearance, it also clears room for larger tires, helping you prep for off-road adventures or just dialing in the stance you've always wanted. With this kit, you're not just getting some spacers and brackets, Rancho includes full heavy-duty radius arms that enhance your suspension strength while keeping alignment dialed in. Rubber OE-style upper mounts maintain a smooth, factory-like ride, while the lower brackets allow for caster adjustment so your handling stays sharp. This is the kind of upgrade that feels as good as it looks, giving you a smoother ride and more clearance all in one go. And with Rancho’s Limited Lifetime Warranty backing the parts, it’s a long-term upgrade you can count on.

Designed To Align Strength Stability And Suspension Geometry

The Rancho RS66553B 2.5-Inch Radius Arm Leveling Kit is a comprehensive suspension solution for 2011–2018 Ford Super Duty 4WD models, built to improve both function and form. This system includes upgraded full-length radius arms that not only enhance structural rigidity but also incorporate OE-style rubber upper mounts to minimize road noise and vibration. The lower brackets at the axle are engineered to allow caster adjustment, which helps maintain proper steering geometry after the lift is installed.

The design supports a bolt-on installation process and retains compatibility with factory components, reducing downtime and complexity during install. It’s intended for drivers who demand more than just cosmetic improvement, this kit enhances control, articulation, and road stability without compromising daily drivability.
