These guys are top notch professionals and I can't put into words the gratitude I have for Dale Swain. I will use them again if needed no doubt and I am telling everyone I know that if they need a crankshaft there is no need to look anywhere else.

Really impressed with the crankshaft and bearing set, packaging was great. Sales person i talked to (Dale) was very informative, answered all questions, even checked for the exact stock they had. No issues. Thanks again.

I have used these guys on my personal engines, and for my company's fleet engine work , for over 35 years, I brought some really bad cranks to these guys , they always went beyond what I expected.
