      Increased Ground Clearance. If you’re planning on outfitting your Super Duty with larger tires, you’re going to need this Rough Country 4.50-inch Suspension Lift Kit with Premium N3 Shocks. By giving your Super Duty up to 4.50 inches of lift, you can accommodate tires measuring up to 35 inches in diameter. This increased ground clearance will also allow your Super Duty to easily drive over boulders, logs, and other off-road obstacles.

      Premium N3 Series Shocks. This Rough Country Suspension Lift Kit comes with front and rear N3 Series shock absorbers. Featuring a nitrogen-charged monotube design, these shock absorbers feature 10-stage, variable valving to give you the smoothest ride possible, whether you’re on or off the road.

      Lifted Coil Springs. Included with this Rough Country Suspension Lift Kit are lifted coil springs designed to lift your Super Duty’s front end up to 4.50 inches. These lifted coil springs are manufactured from high-quality materials to ensure superior performance and durability.

      Fabricated Rear Lift Blocks. Providing the rear lift are fabricated lift blocks that offer up to 4.50 inches of lift. Each lift block is manufactured from fabricated steel designed to be stronger than cast blocks. A black, powder-coated finish helps protect these lift blocks from rust and corrosion.
