6 Inch Lift Kit | Diesel | 4 Link | OVLD | Ford F-250/F-350 Super Duty (17-22)

Conquer challenging terrain with the 6 Inch Lift Kit for Ford F-250/F-350 Super Duty (2017–2022) in diesel configuration. This system isn’t just about height—it redefines how your truck handles, rides, and looks off-road while maintaining factory-like steering precision on the highway.

Rough Country’s 4-Link front suspension swaps the stock arms for a robust 4-Link setup, featuring fixed upper arms and adjustable lower control arms. This combination delivers significantly more wheel travel, improved articulation, and stable handling across rough surfaces. The ride quality remains refined thanks to nitrogen-charged N2.0 shocks, engineered to balance off-road control with a smooth highway experience.

Key features that set this kit apart

• 4-Link front suspension with fixed upper arms and adjustable lower control arms for precise geometry and enhanced axle articulation.
• Radius arm drop brackets that preserve proper caster, maintaining confident steering feel and reducing bump steer after lifting.
• 6-inch lift designed to maximize ground clearance while keeping factory handling characteristics intact on paved roads.
• Ultra-durable anti-wrap rear blocks to prevent axle wrap and binding under heavy acceleration or off-road torque.
• Stainless steel extended brake lines and brackets ensure safe, reliable braking with the increased ride height.
• N2.0 nitrogen-charged shocks deliver the perfect balance between off-road performance and highway comfort—less body roll, more control on rocky trails, and a smoother daily commute.
• All necessary hardware included so you have everything required for installation, with Rough Country’s Lifetime Replacement Warranty for long-term peace of mind.

Why this kit is the right choice

If you’re chasing serious off-road capability without sacrificing highway manners, this OVLD diesel kit is engineered for you. The 4-Link design isolates driveline torque from impacting steering, so you’ll notice steadier tracking, sharper cornering, and improved traction on uneven surfaces. The upgraded springs and anti-wrap blocks lift the axle with stability, reducing lean and axle tramp on climbs and descents.

Who this is ideal for: diesel-powered Super Duty owners who want meaningful ground clearance for rugged trails, the ability to fit larger tires with proper backspacing, and a suspension that stays composed under load. It’s also a smart upgrade for those who tow or haul heavy payloads and demand consistent braking and steering response at height.

Real-world scenarios include navigating rocky trail sections where factory clearance falls short, crossing rutted dirt roads without shocking the chassis, and maintaining confident highway steering after a lift. Compared to standard 2- or 3-tier lift systems, this 4-Link setup provides superior wheel travel, better axle alignment under load, and a more predictable, planted ride—both on street and off-road.

Installation is streamlined by including the essential components for a complete upgrade: lifted coil springs, radius arm drop brackets, extended brake lines and brackets, and nitrogen-charged N2.0 shocks. After installation, a professional alignment is recommended to maximize caster settings and preserve factory-handling characteristics.
