[QUOTE="RM_guy, post: 1369794, member: 20652"] Yes. They are forged instead of cast and will last much longer than the stock cast piston. They will both wear the same amount since they are both made out of aluminium but the difference is in when and how they fail. The cast piston will develop cracks that you can not see and after a time the skirts will suddenly blow apart. The forged piston is much tougher due to the forging process that elongates the grain structure. These elongated grains will hold it together a lot longer and when it does fail it's not as catastrophic. Be aware that with a forged piston you have to be more careful when breaking it in. You have to go through several heating and cooling cycles to relieve the internal stresses. If you don't it will seize up but once it's properly broke in it is no different than a cast piston.
