This means splitting lift kits into various kit boxes to enable them to be shipped easily and also so that you can mix and match kit boxes and assemble them into a variety of different lift styles. This part is on box of a complete lift kit and generally is not ordered by itself as several other boxes are required in order to make a complete BDS lift kit.
