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-stress engine applications.

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

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

Are these pistons compatible with all LS engines?

These pistons are designed for Chevrolet LS engines with a specific 4.130-inch bore. While they are a popular choice for many LS builds, it's important to verify that this bore size and the compression height match your engine's requirements and desired compression ratio.

About this part

Product Details

If you're building a high-performance Chevrolet LS engine, this Manley Piston Set is a solid choice for serious power. These pistons are designed for a 4.130-inch bore and feature a -20.00cc dish volume with a 1.315-inch compression height, making them suitable for many custom LS engine builds where specific compression ratios are targeted.

Manley uses domestic 2618 alloy forgings, which are known for their strength and ability to handle high cylinder pressures and temperatures. The pistons feature proven cam and barrel skirt profiles, designed to reduce friction and wear on your cylinder walls while still generating substantial power. They also boast exacting ring land and groove dimensions, which are critical for achieving a good seal with your piston rings, leading to more efficient combustion and increased power output. For added durability, these pistons come with tool steel wrist pins, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the piston skirt, which is essential for proper ring function.

This set is a popular choice among professional engine builders and tuners who demand reliable performance from their LS engines. 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 details.
