What is the compression ratio impact of the -12cc dish?

The -12cc dish is a volume measurement that affects your engine's compression ratio. A dished piston generally lowers compression. The exact impact depends on your cylinder head volume and gasket thickness, so it's best to calculate this based on your specific combination.

Are these pistons coated for durability?

These Platinum Series pistons feature moly skirt coatings on select part numbers for added durability. The specific coating for this part number should be confirmed with the manufacturer's detailed specifications, but the 2618 alloy forging and chrome moly wrist pins provide a strong foundation.

What is the difference between 2618 and 4032 alloy?

2618 alloy is generally stronger and more ductile than 4032 alloy, making it a popular choice for high-performance and racing applications where extreme strength is paramount. 4032 alloy offers better thermal expansion properties, often making it suitable for street-driven performance applications where quieter operation and tighter clearances are desired.

About this part

Product Details

If you're rebuilding the engine in your Chrysler 5.7L Hemi, a solid set of pistons is crucial for getting the power and reliability you need. These Manley Platinum Series pistons are built for serious performance, whether you're going for a stock rebuild or looking to extract more power from your engine. They're designed to handle the demands of a performance Hemi, offering a well-built foundation for your engine project.

Manley uses domestic 2618 alloy forgings for these pistons, which are known for their strength and ability to withstand high temperatures and pressures. This makes them a strong choice for performance applications. The pistons feature proven cam and barrel skirt profiles, which help generate power while also being gentle on your cylinder walls, contributing to a longer engine life. You'll also find exacting standards in the ring lands and grooves, which are essential for a good seal and maximizing the power your engine makes. Each set comes with premium chrome moly wrist pins, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the skirt, a detail that matters for optimal ring seal and performance.

This set is designed for a 3.922-inch bore with a stock 90.9mm stroke and features a -12cc dish, which is important for setting your compression ratio. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. If you're building a performance Hemi, these Manley pistons offer a well-made and durable option.
