Weiscos are shit pistons made out of semisolid shit that's been painted the colour of aluminium. Why the fuck does it matter that they can handle 400 WHP on an SRT-4? It doesn't. Stock pistons handle 400 WHP on an SRT-4. What's so amazing about Weiscos doing it?

When everything is in tune, the Weiscos are probably going to be fine. Probably. Not all the time, though. Sometimes shit works loose when it's "engineered" and built by a bunch of ignorant shitstained fucksmacks, like the people at Weisco.

Point is, they are shit. Too many of them fail. Too many of them melt. Too many of them crack. They fucking suck. They can't even get wrist pin length correct. I wonder what else they fucked up on?

Installing wrist pin locks is not really rocket science. Clip, meet groove. Groove, meet clip. Done and all set, unless the clip, groove, and/or the wrist pin is defective.

And for the record, the ends of the wrist pins are beveled to prevent them from being too sharp. Grinding on a 90 with no bevel will start grinding on the retaining clip, and at some point it will fail. Have fun with that!
