Base Rail Kit to Fit Thule TracRac Sliding Ladder Rack Uprights in Bed of 2013 GMC Sierra 2500  


I have a 2013 GMC 2500. I want to install the Trac Rac that was on an older Dodge.The stake pockets are bigger on this GMC so I need a new mounting kit with the rubber s and the metal expander section. Will this kit work?


Expert Reply:

To install the Thule TracRac Sliding Ladder Rack Uprights you have part # TH43002XT in the bed of your 2013 GMC Sierra 2500 will require you go with new base rails that fit the dimensions of your new truck as the Dodge rails won't work. So if you have a long bed the rails you'd need are # TH21000 or if you have a short bed you'd need the # TH21501 and you'd be set.

There isn't a way to just swap fit kits for the base rails since they are all made specific for truck year/make/models.
