No, need the AVS piston

The wrist pin is too far away from the top of the piston so the stock piston will push out of the top of the cylinder.  the 6280 connecting rod is longer than the stock rod too.  I just made the mistake of thinking the stock piston would work myself and had to order the AVS piston hahaha    You need to order the wrist pin with the piston separately though.  The piston assembly doesnt come with it
