The purpose-built TeraFlex JK 4dr: Nebo Roof Rack System incorporates OEM aesthetics and styling with rugged performance to increase cargo carrying capacity for your adventures. The factory finished appearance makes it look at home in the city or on a fully loaded rig off road. The low-profile streamlined design has been tuned to reduce air resistance and noise when unloaded. The main rail�s 10-series T-slot mounts readily accept accessory mounting hardware to mount additional gear such as a shovel, axe, or recovery jack as well as aftermarket crossbars from popular companies � including Thule or Yakima. This allows for the widest range of mounting options on the market for carrying toys such as cycling, watersports, and snow sports equipment. The available Cargo Slat Kits (listed below) provide a platform to hold gear as well as direct mounting of popular sport equipment carriers without a crossbar.
