Works perfectly on 2001 Nissan Xterra
I bought 2 sets for my 2001 Xterra, and they fit perfectly on the factory crossbars right out of the box. No need to purchase longer bolts. The included bolts are just long enough, and I had to squeeze the brackets together to get the bolts started, but then it's not a problem. When folded, I can still enter my 7' garage door with plenty of clearance. With the built-in ramps, I can easily load my 12' Old Town Dirigo by myself, and the racks position two kayaks perfectly and hold them securely. The included straps are very good, too. The entire system seems to be very rugged and a lot of attention obviously went into the details of the design. My only complaint, though minor, is that the racks whistle a little bit driving down the highway while folded and empty. Overall, this is a great product!
