We don't have much beyond the basic listing on this part number. The JRC prefix tells us where it comes from in the supplier system, but we don't have the fuller mechanical detail (ring specs, pin size, skirt dimensions) that we'd normally pass along.
Given how sparse our notes are here, call the shop and we'll confirm the application before you order. Piston fitment is not the place to guess.
Sorry if we got something wrong here. If you think this information isn't correct, .
