What material are these pistons made from?

These Manley pistons are forged from domestic 2618 alloy. This material is chosen for its superior strength and performance characteristics, making it well-suited for high-performance engine builds.

What is the purpose of the cam and barrel skirt profiles?

The cam and barrel profiles on the piston skirts are designed to optimize piston movement within the cylinder bore. This design helps to reduce wear on the cylinder walls while still allowing the piston to contribute to substantial power generation.

Are these pistons compatible with all LS engines?

These pistons are specifically designed for Chevrolet LS engines with a 4.070-inch bore. While they offer a -4.00cc dish volume for tuning compression, it's essential to verify that this bore size and dish volume are appropriate for your specific engine build and intended application.

About this part

Product Details

Built with domestic 2618 alloy forgings, these Manley pistons are designed for serious performance builds in Chevrolet LS engines. The 4.070-inch bore size and -4.00cc dish volume are specific choices that matter for tuning compression ratios and achieving desired engine characteristics. Professional engine builders trust Manley for their commitment to strength and durability, making these a solid choice for anyone looking to push their LS engine further.

Manley's signature cam and barrel skirt profiles are a key design element here. They help the piston move smoothly within the cylinder bore, reducing wear on the cylinder walls while still generating substantial power. The ring lands and grooves are machined to exacting standards, which is crucial for ensuring a tight seal with your piston rings. This improved ring seal directly translates to better compression and more efficient power delivery. For added durability, these pistons come standard 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 long-term reliability.

This set includes everything you need to get started with forged pistons for your LS build, including the tool steel wrist pins. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
