Yes, they are Porterbuilt. However, the website he gave you doesn't work anymore. You need to go to porterbuiltfabrication.com now. The hinges are BEAUTIFUL and the function is GREAT. It wasn't too bad putting them on. I spent a lot of time measuring everything like 10 times to make sure it was good. My only complaint is that with the gas shock option the hood doesn't open very far. I'll take some pictures later so you can see. There isn't really anything you can do about it though since there is only so much room for those shocks. It's not bad, I just thought it would open more. Now, that I think about it, I have another complaint...it doesn't align the hood for you
. Its a pain in the A$% trying to align it by myself. It's pretty close right now but I need to do a little more adjusting.
