Our XJ rear cross member is part of our coil conversion kit. This cross member was designed to be used in conjunction with our 1/4 skid plate and skid plate side bars to properly secure this in place. Can NOT be used by itself!Our coil comversion kits use this cross member, suport rails attached to our front 3 piece cross member and our 1/4 Inch skid plate to properly distribute the force put on the unibody.
