These are the hard to find sold-out EXR/SMS “Exposed Racks” brand crossbar roof racks for Jeep Wrangler JK 4 Door. This set with snap in kayak racks would run about $1350 new asking $200. These are the multi-function crossbars which means they have the ability to receive the click-in add-ons. These will fit Jeeps 2007 through 2018. I had these on a 2017 JK. These are hand bolt-on design for your Jeep Wrangler Unlimited JK 4-Door. These racks install under your soft top and allow you to put your top up and down without any interference. The racks can be installed in a few minutes without any tools necessary. I used them to haul kayaks and paddle boards and a few times to haul full sheets of plywood and large boxes from Costco. I have included 6 push-pin kayak mounts. This will allow you to haul 2 kayaks. I also hauled a stand up paddleboard in between them. 4 are the offset quick clip mounts(rear rack) and 2 are the center pin mounts (front rack)
The front rack uses your existing hardtop/freedom top mounting knobs and comes with two hand knobs for the rear rack. A bunch of videos here to see how they can be used for a soft top. https://www.smsparts.com/videos
