What material are these pistons made from?

These Manley pistons are forged from a domestic 2618 alloy. This material is chosen for its superior strength and performance characteristics, making it well-suited for high-stress 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 the piston's movement within the cylinder. They help generate substantial power while also minimizing wear on the cylinder walls, contributing to engine longevity.

Are these pistons suitable for all LS engine builds?

These pistons are specifically designed for Chevrolet LS engines with a 3.905-inch bore and a -18.00cc dish volume. It's important to confirm these specifications match your engine's requirements and desired compression ratio.

About this part

Product Details

When you're building a high-performance Chevrolet LS engine, the pistons are a critical component that needs to handle serious stress. This Manley Piston Set is designed for just that, using a domestic 2618 alloy forging that's known for its strength and ability to perform under demanding conditions. The 3.905-inch bore size and -18.00cc dish volume are specific to certain LS engine configurations, making them a precise choice for your build.

Manley puts a lot of thought into how these pistons work inside the cylinder. They feature proven cam and barrel skirt profiles, which help generate power efficiently while also being gentle on your cylinder walls, reducing wear over time. The ring lands and grooves are machined to very strict standards, which is key for getting a good seal from your piston rings. A good ring seal means more power and better control over combustion. These pistons also come with premium chrome moly wrist pins, and for some part numbers, Manley offers upgrades to even stronger alloys like 9310 or Turbo Tuff/DLC for added durability in extreme applications.

The manufacturing process itself is also notable. Manley uses a unique fixturing method that allows them to machine the skirt and cut the ring grooves in a single operation. This ensures the ring grooves are perfectly square to the piston skirt, which is essential for optimal ring function and sealing. If you're aiming for a serious performance build and want pistons that professional engine builders trust, this Manley set is a solid option.
