The Rhino-Rack VORTEX StealthBar Roof Rack System is designed with superior aerodynamics, practical ruggedness, ease of use and a great low-profile look. The Rhino-Rack Vortex StealthBar is a locking raised railing mounted aero bar car roof rack compatible with most vehicles with factory raised railings. The Vortex StealthBars attach to roof rails by a set of rubber coated stainless steel locking straps, so powerful Rhino has been able to certify the StealthBar system with a load rating of up to 176lb (note: some vehicle manufacturers rails may not be rated for this much weight). The VORTEX StealthBar complete roof rack includes a pair of vehicle specific aerodynamic crossbars, mounting hardware, and locks. The recommended length aero bars will be provided based on Rhino-Racks fit guide. All Rhino-Rack kayak carrier attachments and other accessories offered by The Rack Warehouse fit the Rhino-Rack StealthBars.
