Piston & Connecting Rod: Description

WARNING: This page is about a different car, the 2003 Dodge Intrepid, 2003 Chrysler Intrepid, 2003 Chrysler Concorde, and 2003 Chrysler 300M. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Valve reliefs were removed from the pistons for the 2003MY. It is possible when ordering a service piston/rod assembly that valve reliefs are present. These may be used in the engine, and will not affect engine operation.

The pistons are made of a high strength aluminum alloy. Top land height has been decreased to reduce emissions. Piston skirts are coated with a solid lubricant for scuff resistance. Connecting rod is forged steel with a squirt hole and attaches to the piston with a full floating pin retained by lock rings.
