This 6” Lift for the 2017-2021 Ford Super Duty F-250 | F-350 4WD features Superlift’s precision engineered, heavy-duty tubular 4-LINK arms designed to give your ride a truly custom look and easy install.  These heavy-duty 4-LINK arms utilize a press-fit REFLEX bushing for superior vibration dampening, flexibility, and durability.

IMPORTANT DISCLAIMER: The provided tire/wheel fitments are approximate. Actual dimensions of a given tire size can vary considerably from one brand to another. Manufacturers’ wheel offset and backspacing measurement points are not always consistent. Backspacing greatly impacts tire-to-fender clearance when turning. Wheel width and backspacing influence whether the tires protrude past the fenders, and to what extent. Considering these important factors, we recommend that you fit-check your tire/wheel selection prior to purchasing.
