"These guys are extremely helpful and a pleasure to work with. I bought a 5.9L Cummins long block from them, just had its first 500 mile service, not a single issue so far. Quality craftsmanship 10/10."
"Great company, I have bought several reman 5.9 Cummins motors from them and have zero complaints — great quality and they 100% stand behind their work. I will continue to drive 7 hours one way for long block motors!"
"Thought it was fake because we're in Alaska and they're in Texas. Ended up being cool dudes and ordered a 5.9 engine built with a new turbo. Sent it all the way to Alaska at a reasonable price — runs pretty dang smooth."
