I don't understand why the the specific oem pistons (A,B,C, or D) have to be matched to the correllating number stamped on the cylinder...Does anyone know? So, does it still matter if you use an aftermarket piston?

Oh, I meant to include this!


0-5 =A piston
6-10 =b piston
11-15 =c piston
16-20 =d piston
