Just looked at it & don't see new mentioned
I'm not trying to start an argument over new or used
I would hope that it is a new used crank
The stock Duramax uses a dowel pin on the crankshaft and it is common to see high mileage or high horsepower engines with damaged or sheared dowel pins. DHD offers the best solution for that problem by selling our customers an upgraded crankshaft that will last for many years to come. Our machine shop has modified and added a keyway to each of these crankshafts for added shear strength over the stock dowel pin.
Just going off what I've read from other members using this crank. Where would dhd come up with hundreds of used Lml cranks anyway?
