Will Trac Rack SR Work On 2019 GMC Sierra 1500 with BAKFlip MX4


I have a 2019 GMC Sierra with a back flip MX4 tonneau cover. Will the Trac Rack SR system work with this cover? Will I be able to open and close the tonneau cover. I realize it might hit the crossbars but I’m more concerned with the side rails.


Expert Reply:

Yes, the Thule TracRac SR Sliding Truck Bed Ladder Rack part # TH43002XT-782 for 5-3/4' beds or part # TH43002XT-781 for 6-1/2' bed will work on a 2019 GMC Sierra 1500 with BAKFlip M4 Tonneau Cover.
