Question:

Expert Reply:

While I can give you the height of the Thule roof rack above the roof of your 2023 GMC Sierra 2500, I don't know how much height the cantilever of the ladder rack adds, so you'll need to measure how high above your roof it is and compare that with the Thule roof rack.

For the rack, from the roof of your '23 GMC Sierra 2500 to the top of the crossbar you'll be adding 5-1/2 inches when it is installed, so that should tell you if the height is approximately the same or not. The parts that make up the Thule roof rack that fits your truck are the following:

- Thule WingBar Evo Crossbars - Silver # TH711500 or Black # TH711520

- Evo Clamp Feet for Thule Crossbars # TH710501

- Fit Kit for Thule Evo Clamp Roof Rack Feet # TH145071

- (Optional): Thule One-Key System Lock Cylinders # TH450400
