Please consult your engine shop for your bore requirements.

DO NOT bore your engine before receiving your pistons and taking the proper measurements for piston to wall clearance recommended by ROSS and your machine shop.

Piston sizes are approximate, and all pistons should be measured by a competent engine assembler/machine shop and then pistons should be bored and honed to proper size.

These are absolutely not returnable under any condition once ordered. If the pistons show on backorder or out of stock then there is at least a 12 week wait time as of 4-25-2023

Flat top piston shown in picture, depending on your selections the actual dish and pin height will vary, there will be a set of 6.

The fitment tool will say this doesn’t fit your car, but it doesn’t mean anything as this is a custom application.
