They seem like they are well made. Worked perfect and easy to install on my lq9.

Really liked the quality and price of these versus the other higher priced brand. They threaded in fine with just a little help from the supplied Allen keys. Only issue I had was with the smaller studs when torquing the heads down. The supplied 10mm socket kept slipping on the nut and ended up using a 3/8 socket which was a tighter fit and worked perfectly. 10mm is 0.39 and 3/8 is 0.375

Sockets in kit dont fit nuts, rounded one of the nuts torquing it. A 3/8 twelve point and 5/8 twelve point seemed to fit best.

Completely wrong studs. They won't even screw into the stock thread location if they where the right length. I didn't realize this until I went to put a head on so there goes $180
