If you need any diesel injector repairs or needing to order new ones, these are the guys to use! Sent my lly duramax injectors in for them leaking after new nozzles. While they were there i wanted them gone through, cleaned, and re-adjusted and their service blew my mine. Not only were they honest and told me everything wrong with them, sent 30+ photos of them disassembling my injectors and showed everything that could be a possible issue and they offered suggestions on what to do, prices of everything, and waited for my approval on what i would want to do. I decided to get them cleaned anyway and repaired and they turned our perfect! Had an issue with a nozzle nut after getting them back, called them up, sent them that one injector back, they replaced the part and sent it back to free. In less than a week.
