Replacement Rubber Strip for Thule Aeroblade Cross Bars , thule aero bars (2 * 140cm) (Will fit Roof Racks with 7/16 of an inch wide on the top and 7/8 of an inch wide at the bottom)

I bought this with fingers crossed based on other reviews. Based on my experience, this is a great replacement for the Thule aerobars underside. The factory bottom doesn’t have the ribs, just the top, so this is a good replacement. I wouldn’t recommend for the top side because of the missing ribs.

I used this to reduce wind noise by installing on gap on the bottom of the Thule Xsporter Pro Truck Rack, and making sure the top had no “open” slots….It has helped a lot. Obviously, with boards on the roof it is still not silent, but it has reduced a great deal of the annoying ‘almost whistle’ I had.
