6 Inch Lift Kit | 4 Link | Ovld | Ford F-250 Super Duty 4wd (2015-2016)

Built for F-250 Super Duty owners who want 6 inches of lift without sacrificing factory handling, this 4-Link kit replaces your factory control arms with Rough Country's adjustable lower arms and fixed upper arms, paired with lifted coil springs and radius arm drop brackets that preserve proper caster geometry. Support up to 35"–37" tires while maintaining the balanced suspension geometry your truck needs for both highway and off-road driving.

Installed and serviced at Road Runner Wheels & Tires. Most lift kits go in the same day. Call (678) 400-6467 to schedule.

What's included

• 6-inch D-Coil springs — lifted coil springs engineered to raise the front end and level the truck with the rear.
• 6-inch Upper Arm Kit — fixed upper control arms that maintain proper suspension geometry and caster alignment.
• 6-inch Lower Arms — adjustable lower control arms that allow fine-tuning of caster and camber during installation.
• Radius arm drop brackets — preserve factory-correct caster geometry to keep handling and driveability stock-like.
• N3 Shock Kit — nitrogen-charged shock absorbers tuned for balanced on and off-road performance with a smooth highway ride.
• Anti-wrap rear fabricated lift blocks — replace factory blocks with stronger, specially designed pieces that eliminate axle wrap and binding while maintaining ride quality.

• Extended stainless steel brake lines and brackets — ensure proper brake-line clearance at full suspension travel.

Important notes

• This kit ONLY fits 2015–2016 F-250 Super Duty models equipped with rear factory contact overload springs. It does not fit F-350, dually, or gas engine models.
• The fabricated lift block replaces your factory-equipped block. No compatibility with cast OE blocks.
• Radius arm drop brackets are required to maintain proper caster geometry; they are included and must be installed for correct handling.
