Upgrading a Thule Atlantis 1800 to AcuTight Mounting Hardware

Question

Question:

Can I change the quick grip clamps on an Atlantis 1800 to the acutight clamps. I like the acutight easy clamping and would like to have this instead of just the quick grip that doesnt click.

Yes, the AcuTight system is basically just an upgraded QuickGrip system so you could upgrade your Quickgrips out of your Atlantis 1800 to the Acutight system by installing the part # TH7521484001.

Both systems use the same cradles part # TH8523387001.

The difference between the Class II and Class III hitches has to do with their Gross Trailer Weight (GTW), their Tongue Weight (TW), and their Hitch Receiver Size. Class II trailer hitch receivers have a 1-1/4 inch receiver and can be rated up to…
