I don't know if people are shut down for COVID or what, but I was impressed with CHE's customer service, and they seem pretty popular so I ordered them through Scoggin Dickey who had them in stock. I had a minor issue with one of the bushings, so I sent an email to CHE, they called me back within a half hour and we got things squared away. Then he told me if I had any questions or problems to call, and gave me his office number, and cell number. I've been VERY impressed with their customer service. Install was simple, just time consuming, there's lots of videos around of trunnion upgrades, so I won't get into that. But they were very high quality, much better than the sloppy stock ones. After installation, the valvetrain is noticeably quieter. I had been getting some knock retard before that I was pretty convinced was false, and after installing these, the knock retard is mostly gone. I highly recommend them
