EXR Solid Crossbar Package [BLACK] without Square holes is a very strong, American made crossbar system. This package accepts most other mfg. accessories, but DOES NOT accept EXR Click-In Accessories. This package fits vehicles with raised roof rails with an inside width of 37.25" to 53.5" and rail thickness between 1.25" to 2.00". Package Includes:  [EXR Sld HD, 1" to 2" High, BLK xBar Pkg, (4) 51" w/ Z-Brkts & Feet, rail inside width 37.25" to 53.5"]. The component part numbers in the box are: (4) 8-00-9651-BK, (3) 8-00-9794, (1) 8-00-9796, (4) 8-00-9798, (3) 8-00-9915. Crossbars are ~51" wide and come with (5) threaded holes on the bottom that can receive the EXR Weight Distribution feet. Top of crossbars will be 2.46" above factory roof rails. The brackets that mount to the roof rails each have a threaded hole for additional, optional roof rail reinforcement; so this package has a total of (28) threaded hole location options. Package contains (9) Weight Dist. Feet (normally used in any of the threaded hole options, as best fits the vehicle). NEVER PUT WEIGHT DIST. FEET ON OR NEXT TO GLASS OR OTHERWISE BREAKABLE MATERIAL. Feet length is based on averages, but is not guaranteed to work on every vehicle in every spot (your vehicle may have specific fit notes on smsparts.com/searchbyvehicle). For this reason we sell additional weight distribution feet in different sizes; they are available for purchase through our authorized resellers or on our website. 8-00-9915 (pack includes 3 feet that sit 1.5" high) and 8-00-9916 (pack includes 3 feet that sit 2.5" high). Additionally we have a short custom pack 8-00-9913 (pack includes 2 feet plus 2 rubber stops that sit <1" high). Crossbars are made from heavy duty carbon steel, acid washed, electroplated and powder-coated. Carry More with Exposed Racks (EXR)!
