Even from the factory? I suppose as nothing is as it used to be. I might add that the parts are designed for a stockish type vehicle so, adding big tires without properly adjusting gear ratios in the axles, pulling heavy trailers, etc., will take their toll on the stock parts over time and miles. I have no doubt as to the lesser quality of modern aftermarket replacement parts. I do not know if a quality HD aftermarket flex plate is available for these vehicles or not. It would be my choice if I had to make it.
