Works great to fit our 2016 Town and Country roof top bars to my hilly rollers kayak carrier!




by:

I have a 30+ year old Thule tandem rack. I was determined not to shell out another $xxx+ to buy a new one, just because I wanted to convert from the Thule square crossbars to aero bars. After conferring with an eTrailer expert about mighty mount load limitations, I purchased these mounts instead of trying to rig my own solution. I’m using all four mighty mounts to attach a Thule tandem rack onto Yakima Corebars. My Yakima rack system is attached to my truck via the t-slot rails on a RetraxPro XR tonneau bed cover. With the Corebars sitting on Skyline towers, the mighty mounts serve as a perfectly flat platform for the mounting plates on the tandem rack. I attached the tandem rack to the four mighty mounts using 2 ½ inch by ¼ inch Grade 8 hex cap course screws, some fender and flat washers, and a nylon insert lock nut; all purchased from my local hardware store. I did need to tilt the Corebars forward with the Skyline tower adjusters to level the mighty mount top surface. No issues with turbulence noise. Total load on the four mighty mounts totals 70 lbs including both the rack and tandem bike. Thanks etrailer for the advice, the parts, and the great customer service!

I used these to adapt an old Yakima rack to my Subaru Outback roof rack cross bars.
Getting these to work with the older rack saved us some serious money.
Thanks Etrailer!
