For anyone contemplating OEM roof rack accessories, here are notes from my 2Dr Badlands. Be aware that the “movable” crossbar can only be attached to the rails in two fixed locations on the rails, held by two screws at each bracket.
Back of Rear roof x-bar to raised rear tailgate window wiper 26”. 14” to roof rear edge
X-bar 2-3/4” wide
X-bar spread in rear position: rear edge to forward edge 30-1/2”, 24-3/4” between x-bars.
Forward X-bar 27-1/2” ahead of mid position
38-1/2” between rails front and back.
Rails 1-3/4 thick x 2-3/4 wide with 1 to 1-1/2” clearance from roof to bottom of rails.
Movable X-bar 33-3/8 clear between plastic brackets.
27-1/2” spread between rear 2 locations.
X-bars 1.08” thick.
