Custom piston prices do not include pins. A complete selection of optional pins can be found here. When ordering replacement custom pistons, please give our job card number which is engraved on the bottom of the piston in the area which is machined for crankshaft counterweight clearance. This number is also on the ROSS invoice, the end of the piston box, and the computer generated information which is inside the box with your new pistons. If you do not have the old job card number, we will be happy to work from a sample piston, however please add one week to our custom manufacturing time. When ordering replacement pistons, you must specify the cylinder numbers in which they will be used.
