Same piston as the OEM for 2008 300XC-W, but about $100 cheaper.

I WAS A LITTLE SCEPTICAL ABOUT THIS PRODUCT. HOW COULD MOVING THE MOTOR 2.5mm MAKE THAT MUCH DIFFERENCE? AFTER READING SEVERAL REVIEWS ON LINE AND IN MAGAZINES I DECIDED TO GIVE IT A TRY. I COMBINED THIS PRODUCT WITH A MAXISS EN FRONT TIRE AND WOW WHAT A DIFFERENCE. I AM 250 lbs AND DIDN'T HAVE NEAR THE TROUBLE WITH THE "DARTING" THAT ALOT OF OTHER YZ OWNERS COMPLAIN ABOUT. THIS TOOK ME FROM REALLY LIKING MY BIKE TO LOVING IT. DON'T HESITATE. JUST BUY IT. INSTALL WAS FAIRLY EASY USING THE VIDEO ON THE DRD WEBSITE.
