Question:
For installing the Hullavator on a Thule ARB53 on a 2021 Lexus NX-300h, what are the parts needed to properly secure it? I bought the Hullavator used, so I do not know the model number, and it was previously installed on a roof rack with a square bar.

Expert Reply:
Only the latest version of the Thule Hullavator part # TH898 is compatible with aero shaped crossbars. So your options at this point would be the new Hullavators or a square bar roof rack for the vehicle you have to use the Hullavators you currently have. There isn't an adapter for the rack you have now to allow it to be used on aero bars.
For a square bar rack that fits your 2021 Lexus NX 300h you would need the part # TH53CG.
