Question:

Recently purchased Malone airflow 2 cross bars for my 4Runner and am looking for an alternative to the Thule square nuts for hullavator mounting.

Expert Reply:

Hey Rick, welcome back! The older Thule Hullavator 897XT and the current Thule Hullavator item # TH898 cannot be attached to aero bars like your Malone AirFlow2 item # MAL84AR without using the t-slots.

The Thule Hullavator item # TH898 comes with all the necessary parts to attach to t-slots.

To attach the older version of the Thule Hullavator 897XT to the top channel of your AirFlow2 item # MAL84AR you'll need four of each of the the following parts:

Replacement Socket Head Cap Screw - M6 x 30 item # TH919063054

Replacement Square Nut item # 853-7557

Replacement M6 Washer item # 951061254

I attached a screenshot from the original instructions so you can see how these parts are installed in a T-Slot crossbar.

What model Hullavator do you have?
