- Vehicles produced before 3/1/99 require a different box kit. You must check the production date on the door prior to ordering.
- The Superduty came from the factory with a 2", 3", or 4" rear block. If you wish to truly level your vehicle it may be necessary to change the rear OE block.
- Will not fit dually applications.
- These trucks were produced both with and without a top-mounted overload spring. There is an extra leaf that mounts on top of the rear leaf pack. You will need to know how your truck is equipped before ordering.

This vehicle was manufactured with either square front U-Bolts or radiused front U-bolts. Typically, 1999-2000 are square and 2001-2004 are radiused, but that is not always the case. The radiused U-bolts aren't square or round, but rather have a gentle radius that matches a cast factory upper U-bolt plate on top of the factory spring. Vehicles manufactured prior to 2-28-99 require yet another different box kit due to a change in the factory track bar.
Please make the appropriate selection for your particular vehicle.
