According to my contact at Retrax, if you have a RetraxPRO MX Hard Tonneau Cover on your 2018 GMC Sierra 1500, then you can use the Replacement Trax Side Rails to add Trax Rails to your tonneau cover. I will just need to know what size bed you have so I can look into the correct replacement rails for your application.

The Replacement Side Rails part # RTT-82381 you were looking are for a Ford, so they won't work for you.
