The TeraFlex JK rear utility cargo rack.

The TeraFlex JK rear utility cargo rack provides additional storage options to organize and secure cargo. Taking mounting cues from the Nebo roof rack, the cargo rack also provides universal accessory mounting compatibility. The extruded aluminum rails take advantage of industry standard 10 series T-slot mounting to allow the use of readily available hardware to mount small accessories or recovery equipment.
