What material are these pistons made from?

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

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 bore. This helps reduce friction and wear on the cylinder walls while ensuring the piston maintains proper alignment for efficient combustion.

Are these pistons suitable for all LS engine builds?

These pistons are designed for performance LS engine builds requiring a 4.165 inch bore and specific compression height and dish volume. It's important to verify these specifications match your engine's requirements and intended use. Note that they are not CARB approved and cannot ship to California.

About this part

Product Details

If you're building a high-performance Chevrolet LS engine, this Manley Piston Set is a solid choice. These are forged pistons, meaning they start as a solid block of aluminum that's heated and then pressed into shape. This process creates a much stronger and more durable piston than cast aluminum, which is essential when you're pushing an engine hard.

Manley uses a domestic 2618 alloy for these pistons, which is known for its excellent strength and ability to handle high temperatures and pressures. The pistons feature proven cam and barrel skirt profiles. These profiles are designed to help the piston move smoothly in the cylinder, reducing friction and wear on the cylinder walls while still allowing the engine to make good power. The ring lands and grooves are machined to very precise standards, which helps ensure a good seal with the piston rings, leading to better compression and more power. They also come with tool steel wrist pins for added durability, and some part numbers include moly skirt coatings to further reduce friction.

This set is designed for a 4.165-inch bore with a 1.115-inch compression height and an -18.00 CC dish volume. They are a popular choice among professional engine builders and tuners who need reliable performance. Keep in mind these are not CARB approved and cannot be shipped to California.
