Recommended Roof Rack to Fit 2 Sets of the Thule Hullavator on a 2013 GMC Terrain

Since the Thule Hullavator Pro Kayak Carrier # TH898 requires about 31" of crossbar space, the 53" WingBar Evo bars # TH711400 that you referenced are not long enough to accommodate it. The Thule aero bars also have limited mounting space on the underside so you wouldn't be able to go with larger crossbars but we do have an alternative solution for longer crossbars.

Yakima has their JetStream bars which are comparable to the WingBar Evo bars and they have a strip that runs the full length of the underside of the crossbar. The best length for you would be to use their 60" JetStream bars, part # Y00426, along with the TimberLine Towers # Y33TR if you have raised rails or the BaseLine Towers # Y28TR and Fit Kit # Y06146 if you have a naked roof.

I spoke with my contact at Thule who said that you would be able to fit 2 Hullavator sets on 60" crossbars but the biggest concern is the weight. One set of Hullavators weigh 40 lbs so when you use 2 sets you are already sitting at 80 lbs of weight on your crossbars. The Yakima roof racks have a weight capacity of 165 lbs but your Terrain may be rated lower. You will need to check your owner's manual and make sure that the 80 lbs of Hullavator plus the weight of your kayaks doesn't exceed the capacity of your roof rack or your Terrain.

A few other things to note is that the Hullavator needs to sit 4" - 8" beyond the feet of your roof rack so that it doesn't make contact with your vehicle, and your crossbars shouldn't extend past your side mirrors. You will need to do some measuring to ensure you stay within these lengths.
