What material are these Manley pistons made from?

These pistons are forged from domestic 2618 alloy. This forging process results in a stronger and more durable piston compared to cast alternatives, making them suitable for high-performance engine builds.

What is the purpose of the -12cc dome dish volume?

The -12cc dome dish volume is a specific design feature that affects the combustion chamber's shape and volume. It's used by engine builders to precisely tune the engine's compression ratio and combustion characteristics for optimal performance.

Are these pistons compatible with all Mitsubishi Eclipse models?

These pistons are specifically designed for Mitsubishi Eclipse engines with an 85.25mm bore. It's important to confirm your engine's bore size and specifications to ensure proper fitment for your build.

About this part

Product Details

If you're rebuilding the engine in your Mitsubishi Eclipse and looking for a solid foundation, this set of four forged pistons from Manley Performance is a strong option. These pistons are built with an 85.25mm bore and feature a -12cc dome dish volume, which is a key spec for tuning compression ratios and combustion chamber design. Manley is a well-known name among engine builders for a reason; they focus on the details that make a difference when you're pushing an engine hard.

What sets these pistons apart starts with the material: they're forged from domestic 2618 alloy. Forging makes them much stronger and more durable than cast pistons, which is essential for high-performance applications. They also come standard with premium chrome moly wrist pins, and Manley's unique fixturing process ensures the ring lands and grooves are machined with exacting precision. This attention to detail helps achieve a better ring seal, which translates directly to more power and better engine efficiency. Plus, the cam and barrel skirt profiles are designed to be effective at generating power while also being gentle on your cylinder walls, reducing wear over time.

This set includes everything you need to replace the pistons on four cylinders. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For optimal results and longevity, always refer to the manufacturer's installation instructions and recommended assembly procedures when rebuilding your engine.
