What material are these Manley pistons made from?

These Manley pistons are forged from domestic 2618 alloy. This material is chosen for its exceptional strength and ability to perform under high stress and temperature conditions common in performance engines.

What is the purpose of the moly skirt coating?

The moly skirt coating on select Manley pistons helps to reduce friction between the piston skirt and the cylinder wall. This can lead to improved engine efficiency, reduced wear, and potentially longer engine life.

Are these pistons suitable for all LS engine builds?

These pistons are designed for performance Chevrolet LS engine builds with a 3.905-inch bore. While they are a popular choice for many applications, it's always best to consult with your engine builder or refer to detailed build specifications to ensure they are the right fit for your specific project.

About this part

Product Details

If you're building a high-performance Chevrolet LS engine, a solid set of pistons is crucial for handling the increased stress and power. These Manley Performance pistons are built for serious engine builds, offering a robust foundation for boosted or naturally aspirated setups that demand more than stock can handle. They feature a 3.905-inch bore size, a 1.115-inch compression height, and a -4.00cc valve relief, making them a popular choice for many LS engine configurations.

Manley uses domestic 2618 alloy forgings for these pistons, which is known for its strength and ability to withstand high temperatures and pressures. The pistons also come with tool steel wrist pins, and many part numbers include a moly skirt coating. This coating helps reduce friction and wear on the cylinder walls, contributing to both improved performance and longer engine life. The ring lands and grooves are machined to very precise standards, which is essential for getting a good seal with your piston rings, leading to better compression and more power. Manley's unique machining process ensures the ring grooves are perfectly square to the piston skirt, further enhancing the seal and reducing the chance of blow-by.

These pistons are designed with proven cam and barrel skirt profiles. This means the shape of the piston skirt is optimized to reduce friction and noise while still providing excellent support within the cylinder bore. This attention to detail in the design and manufacturing process is why many professional engine builders trust Manley for their critical projects. 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.
