Important fitment note: The years and models above identify potentially applicable configurations, not every trim or engine sold in those years. Confirm the OE part number, build date, equipment options and mounting details before ordering.
Product Overview
This piston and top-end rebuild kit is used for repair of cylinder sealing and compression on the applicable equipment or vehicle. It replaces the corresponding original component when its specification and mounting arrangement match.
Low compression, piston wear or scoring can require a top-end rebuild after the cylinder is measured. Replacing the defective component can restore normal operation once the underlying cause has been identified. Related systems should be inspected so an unrelated fault is not mistaken for a bad replacement part.
Measure the actual cylinder bore and piston-to-wall clearance; do not order solely by model year.
