Question:

I am looking for a T-Slot rail upgrade or another rail upgrade for my Retrax Pro MX system I have on my 2016 GMC Sierra 1500 Denali.

I contacted the manufacturer and they informed me that you can replace the rails on your Retrax MX cover with XR rails that have the T-slots.

If you have a 5-1/2' bed on your 2016 GMC Sierra 1500 then the Replacement Side Rails for Retrax XR Series Hard Tonneau Covers # RT44FR would fit your truck. If you have a different size bed or would like confirmation that these are the correct rails, please provide me with your truck bed information and what model number MX cover you have and I would be happy to help you with that.
