CP Piston & Ring Set for Dodge SRT4 - Bore (88.5mm) - Size (+1.0mm) - Compression Ratio (8.5)

This package includes a set of four forged pistons and the necessary piston rings to match. These are specifically made for the Dodge SRT4 engine, featuring an 88.5mm bore size, which is 1.0mm larger than the factory specification. The compression ratio is set at 8.5:1, making them suitable for builds where boost is a significant factor or for those looking to tune for specific fuel requirements.

CP Pistons are well-known for their robust construction, and these forged pistons are no exception. Forging the aluminum creates a much stronger and more durable piston compared to cast alternatives, which is crucial for handling the increased cylinder pressures common in performance applications like the SRT4. The 1.0mm oversize means these are intended for engines that have been bored out to accommodate them, often as part of a performance rebuild or to refresh an engine with worn cylinders. The included rings are designed to seal effectively with these specific pistons, helping to maintain compression and manage oil.

When installing these pistons, ensure your engine block has been properly machined to the 88.5mm bore size. It's also important to consult the manufacturer's installation instructions for specific clearances and lubrication requirements, especially given the performance nature of this component. Remember that these pistons are not CARB approved and cannot be shipped to California.
