6 Inch Lift Kit | Gas | Radius Arm | 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 6-Inch Radius Arm Drop Suspension Lift for gas-powered engines. This comprehensive kit is designed to give you serious height without sacrificing the smooth, everyday ride you rely on. Take on rougher terrain, handle bigger wheels, and still enjoy a refined driving experience that feels closer to stock than you’d expect.

Why this 6-Inch Radius Arm Drop Lift stands out

What sets this kit apart is how it preserves suspension geometry while delivering substantial lift. The heart of the system is a pair of beefy tubular radius arms—each roughly 2 inches in diameter—that bolt directly into the factory mounts. This careful alignment keeps the suspension angles close to stock, which translates to improved steering response, stable handling, and smoother vibration damping on rough roads. If you’ve towed, loaded up a camper, or simply want confident daily driving at higher ride heights, this geometry-conscious design matters.

Key features and benefits

• 6-inch lift with radius-arm drop: Elevate your Super Duty and gain ground clearance while maintaining controlled, predictable handling.
• Up to 37-inch tires: Expand your tire options for off-road traction or bold street presence without compromising fundamentals.
• 2" O.D. tubular radius arms: Durable, oversized arms reduce flex, increase strength, and provide a more factory-like angle for better ride quality.
• Precision-fit to factory mounts: Designed for straightforward alignment with existing hardware, simplifying installation and preserving OEM geometry where it matters most.
• Durable rubber bushings: Enhanced vibration absorption helps keep cabin noise and harshness in check over rough terrain.
• All-inclusive kit: Everything you need for a total suspension transformation is included, so you can confidently complete the install and hit the trail or highway with confidence.

Why it matters for real-world use

This lift isn’t just about “more height.” It’s about how that height behaves under load, during steering, and while braking. By maintaining suspension geometry close to OEM, you get:

• Predictable steering feel and reduced bump steer on uneven surfaces.
• Consistent wheel alignment angles when the SUV is laden or towing, helping tire wear stay even longer.
• Improved ground clearance for primitive roads, rock trails, and off-road adventures without sacrificing on-road comfort.

Installation and compatibility

Designed for at-home installation, this kit requires cutting and drilling to complete. Plan for an estimated 6–10 hours, depending on your experience and shop setup. The process is straightforward for a weekend project, especially with a dedicated helping hand. This kit is specifically engineered for the 23–26 Ford F-250/F-350 Super Duty with a gas drivetrain, ensuring a precise fit and reliable performance once installed. If you’re upgrading from a factory suspension to a true radius-arm setup, expect a noticeable improvement in ride quality and off-road capability.

Warranty and peace of mind

Rough Country backs this 6-Inch Radius Arm Drop Suspension Lift with a Limited Lifetime Replacement Warranty against manufacturer defects. That means you’re covered for the lifespan of the product in terms of structural and workmanship concerns, giving you confidence to push your truck harder and longer without fear of hidden defects.

Who this kit is ideal for

• Truck enthusiasts who want a bold 6-inch rise with a ride quality closer to stock than other lifts.
• Owners planning to run larger tires (up to 37 inches) for off-road excursions, mud, rocks, and steep grades.
• Daily drivers who still demand refined highway manners and predictable handling when carrying payloads.
• DIY enthusiasts seeking a complete, well-integrated suspension upgrade that bolts into existing mounts and aligns with factory geometry.

Practical tips for getting the most from your lift

• Budget time for a thorough alignment after installation to maximize tire life and steering precision.
• Inspect rubber bushings after the first few hundred miles of use; the upgraded bushings are designed for vibration absorption, but periodic checks keep performance consistent.
• Pair the lift with appropriate wheel and tire options that complement your driving goals—whether you’re chasing trail capability or daily driving polish.
