Question:
I have a brand new 2024 GMC Sierra HD four-door long box. Is the -000xt what I’m looking for. Is there confirmation this will work on my truck? Is there a center support available? I’m a contractor and some times haul long flimsy siding boards that may need support in the middle. Thanks

Hey Jim,
The Thule TracRac SR # TH43003XT-000EX is designed for select Ram and F-series trucks so you'll need the # TH43002XT-780EX for your Sierra instead. The cantilever add-on will help provide an extra point of contact for support for the longer flimsy materials you have to haul. The towers being able to easily slide and lock along the base rails will definitely be a huge help to accommodate different length loads.

Hey Jim, how did the Thule TracRac SR work out on your Sierra? Did the cantilever give you the extra support you needed for those long siding boards? Your update could make it easier for other contractors hauling similar loads.
