I've bought ten of them so far and used or sold 6 of them with no problems or come backs to date. I bought the first six in or close to 2002 I haven't bought or used any of there new Billet stel cranks yet, I bought one of there cast 4 inch stroker cranks for my 351 Ford Windsor street rod project motors but I haven't taken it out of the box yet, same thing on a 3 3/4 inch stroker crank for a SB 350 Chevy engine that I bought at the same time. Did you buy one and your machinest tell you it is junk
