The catalog entry we have on this one is brief. We don't have more detail on ring specs, gudgeon pin sizing, or dome shape for this listing, so before you order, check your bore measurement against a rebore gauge and call the shop to confirm it matches what you're working with.
If your cylinders have already been bored oversize before, or you're not sure what the current bore spec is, that's exactly the kind of thing to sort out with us first rather than guess from the part number alone.
Sorry if we got something wrong here. If you think this information isn't correct, .
