For those looking to further enhance the JK 4-Door Trail Cage installation, the Poison Spyder C-Pillar Kit ads strength to the rear passenger portion of the OE cage.  This kit must be welded in to the OE cage at the top, but it bolts in at the lower end.  The C-Pillar kit consists of CNC laser cut lengths of 1.75" OD, .120" wall DOM tubing, and engineered foot plates that are fabricated from CNC laser cut, brake-formed 3/16" plate steel.  Convenient indexing tabs and slots are provided where the DOM tube connects with the foot plate, making assembly quick and easy.
