Hello Michael,

The Curt Custom Base Plate Kit - Removable Arms # C55KR is going to be a great fit for your 2018 GMC Sierra 1500, and your Blue Ox BX7335 Aventa II tow bars will connect perfectly to the Curt base plate.

Are you new to flat towing, or just setting up a different vehicle? I’ve attached a help article on the "Must-Have Flat Towing Components." It’s a great read whether you’re just getting started or just want a quick refresher.

What other components do you already have? I’d be happy to look everything over and get you the part numbers for anything you still need.

Where are you headed for your first adventure once everything is all set up?
