The Zone Offroad box kit for 1999–2004 Ford F-250/F-350 supports a 2.5-inch lift and is offered as the vehicle-specific kit segment for those model years. Intended to provide the parts needed for a modest suspension height increase, this box should be used with any complementary kit sections and hardware to complete the lift and retain proper fitment on compatible Ford Super Duty trucks.
