Yakima will prioritize fitting their crossbars if enough people want it. Follow this link and let them know you want them to fit yakima bars for the Yukon! http://fitlookup.yakima.com?fitid=26728We've had our Yukon for months, and GM has sold tens of thousands of vehicles.
Why is Thule and Yakima taking so long figuring out what crossbars fit? I heard that some people have ordered cheap crossbars on Amazon with no issue, so the rails obviously aren't anything exotic right?.
