They turned out to be of good quality and bolted well. However, the location of the Zerk hardware makes it impossible to bolt them to a 2003 Durango without damaging the fastener. They could put the fittings in 3 other places and that would be nice but I don't think engineering is their specialty. Since I already had the old ones and the price, I decided to use them anyway, but I won't buy them again.
