Description

Transform your Ford F-150 4WD (2015-2020) with Rough Country's 6-Inch Suspension Lift Kit, engineered for aggressive styling and trail-ready performance. This comprehensive kit offers increased ground clearance and the ability to fit up to 35-inch tires with proper spacing, while aiming to maintain ride quality. It includes heavy-duty lifted knuckles, precision-engineered strut spacers, differential drop brackets, sway-bar drop brackets, brake line brackets, and a driveshaft spacer to keep vital components at factory-like angles for a smooth ride. The kit features robust construction, including front and rear 1/4-inch plate steel crossmembers for aggressive style and solid support, specifically designed for the F-150 chassis. The fabricated rear blocks are highlighted for their strength over cast options and incorporate anti-axle wrap geometry to preserve stock ride quality. This lift allows for the fitment of 35-inch tires, enhancing both the aesthetic and off-road capabilities of your truck. Installation requires cutting and drilling. It is important to note that this kit does NOT fit regular or standard cab models due to potential pinion angle issues that can cause drivetrain vibrations. If retaining factory wheels, it is advised to use tires no wider than 11.5 inches. Buyers can choose between nitrogen-charged N3 shocks or the premium Vertex reservoir series for customized ride quality.
