Supertech Ford Zetec 85mm Bore 1.161in Comp Height -9cc Dish 8.7:1 CR Pistons- Set of 4 (Excl Rings)

This set includes four Supertech pistons specifically made for Ford Zetec engines, featuring an 85mm bore and a compression height of 1.161 inches. Each piston has a -9cc dish volume, which helps achieve a target compression ratio of 8.7:1 when used with appropriate cylinder heads and gaskets. These pistons are forged from strong materials, making them a solid choice for rebuilding or upgrading your Zetec engine. Please note that this set does not include piston rings, so you will need to source those separately.

Forged pistons like these are built to handle the increased stresses of performance applications or heavy-duty use compared to cast pistons. The 85mm bore size is standard for many Zetec applications, and the specific dish volume is designed to work with common Zetec cylinder head configurations to achieve the stated compression ratio. This makes them a well-considered component for engine builders looking for reliable internal engine parts. It's important to ensure your engine build plans align with the specifications of these pistons for optimal performance and longevity.

When installing these pistons, remember that proper balancing of the rotating assembly is crucial, especially when working with forged components. Always refer to the manufacturer's detailed installation instructions for critical information regarding clearances, ring installation, and assembly procedures. This set is not CARB approved and cannot be shipped to California.
