I don't know the metalurgy of Wiseco I do know from experience in using Wiseco pistons. I have never had an engine fail because of a Wiseco piston. I have also seen them hold up to abuse no piston should have to take.I had a friend put the retaining clips in backwards in an S&S big bore kit from Harley with Wiseco pistons. The wrist pin ate almost 1/4 into the side of the jug. Almost through the wall into the fins. The rod was bent the engine was still running but making a racket as tou would imagine. The piston and rest of the cylander wall was fine.I can tell you quite a few cases where Wiseco held up to more than they should ever have to.
