6 Inch Lift Kit | M1 Struts/m1 | Ford F-150 4wd (2015-2020)

Built for F-150 4WD owners who want aggressive stance, genuine off-road clearance, and the capability to run 35-inch tires — this 6-inch lift kit combines heavy-duty fabricated components with a carefully engineered suspension geometry that keeps your truck handling like stock. Rough Country delivers a commanding ride height without sacrificing driveline angles or ride quality.

What's included

• Knuckles — precision-engineered for F-150 and Raptor fitment, delivering lifted geometry without compromising suspension travel.
• RC Crossmember Box — 1/4-inch plate steel fabricated crossmember for rock-solid front support and aggressive styling.
• M1 Loaded Strut Pair — 6-inch nitrogen-charged monotube struts engineered to handle the new ride height while maintaining control on road and trail.
• M1 Monotube Shock Pair — rear shocks tuned to match the front strut performance and prevent axle wrap through custom anti-wrap geometry.
• Lift Kit Hardware — differential drop brackets, sway-bar drop brackets, brake line brackets, and driveshaft spacer to maintain factory-like driveline angles and smooth ride quality.

Important notes

• This kit does NOT fit regular or standard cab F-150 models — pinion angle geometry causes drivetrain vibration on those body styles.
• Requires cutting and drilling during installation.
• If you retain factory wheels, do not exceed 11.5" tire width to avoid suspension interference.
• The kit is designed to clear up to 35-inch tires with proper spacing; tire clearance depends on offset and backspacing.

Why customers pick this at Road Runner

• Factory track width and handling preserved — driveline geometry is corrected with drop brackets, so your F-150 rides smooth on pavement and dirt.
• Rough Country Lifetime Replacement Guarantee backed by a local dealer you can call if anything goes wrong.
• Fabricated steel components outlast cast alternatives and are built tougher for rock crawling and towing.
• Professional installation by technicians who assemble these kits every week — alignment performed in-house as part of the lift.
• Shock and strut options — pick N3 nitrogen shocks for balanced performance or upgrade to Vertex reservoir for maximum control.
