Passenger Side Engine Piston – GM (97387001)

Passenger Side Engine Piston is one of the pistons that converts combustion pressure into motion. Ring land dimensions and skirt coating are specific to the build, not to the displacement.

Replace the Side Engine Piston during any rebuild that has the head off, and always when the bore shows vertical scoring. Piston-to-wall clearance is set by measurement, not by the part number alone.

This Side Engine Piston is listed under part number 97387001, filed under Pistons, Rings & Cylinders. If the original number is unreadable, send us the VIN and we will confirm the reference before dispatch.

This is genuine GM stock, supplied for the Side Engine Piston with the manufacturer number intact so the reference on the box matches the catalogue.

This listing is specifically for the passenger (right-hand) side; the opposite side is a separate part number.
