I've had these racks for more than a decade. I have a small car. So, in addition to carrying kayaks, I sometimes use them for building materials too. I think this is only the second time I've had to replace an end. It was knocked off in a drive-through car wash. (only 1) My only issue was that it was unclear how many were in a package. I thought it might only be one or two. I'm happy to have extras though. Who knows how long they might last?
