What material are these pistons made from?

These Manley pistons are forged from domestic 2618 alloy. This material is chosen for its exceptional strength and ability to withstand the high pressures and temperatures found in performance engines.

What is the purpose of the moly skirt coating?

The moly skirt coating on these pistons helps to reduce friction between the piston skirt and the cylinder wall. This can lead to improved engine efficiency and reduced wear over time.

Are these pistons compatible with all LS engines?

These pistons are designed for LS engines with a specific 4.070-inch bore size. While they are a popular choice for performance LS builds, you must confirm this bore size matches your engine's requirements.

About this part

Product Details

If you're building a high-performance Chevrolet LS engine, this Manley Performance Piston Set is a solid choice. These pistons are designed for a 4.070-inch bore and feature a -10.00 CC dish, making them suitable for various compression ratio targets. Manley has been a go-to for serious engine builders for a long time, and these pistons reflect that experience.

What sets these pistons apart is the material and design. They're forged from domestic 2618 alloy, which is known for its strength and ability to handle high cylinder pressures and temperatures without deforming. You also get tool steel wrist pins for added durability, and a moly skirt coating to help reduce friction and wear on your cylinder walls. Manley also pays close attention to the details, like the ring lands and grooves, ensuring a tight seal for maximum power. Their unique fixturing process means the ring grooves are perfectly square to the piston skirt, which is crucial for proper ring seal.

This set includes eight pistons, each designed with specific cam and barrel profiles. These profiles help the piston move smoothly in the cylinder, reducing stress on the walls while still generating substantial power. When you're aiming for serious performance in your LS engine, components like these pistons are fundamental to achieving your goals. Keep in mind these are not CARB approved and cannot be shipped to California.
