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 applications.

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

The cam and barrel skirt profiles are designed to help the piston move smoothly within the cylinder bore. This design helps to minimize friction and reduce wear on the cylinder walls, contributing to longer engine life and consistent performance.

Are these pistons compatible with all LS engines?

This specific piston set has a 4.125 inch bore and a -20.00cc dish volume, which are specific configurations for certain LS engine builds. It is important to verify that these specifications match your intended engine build and application before purchasing.

About this part

Product Details

When you're building a high-performance 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 robust 2618 alloy forging that's known for its strength and ability to withstand high temperatures and pressures. The 4.125-inch bore size and -20.00cc dish volume are specific configurations for certain LS engine builds, often found in performance applications where compression ratio tuning is key.

Manley puts a lot of thought into how these pistons work inside the cylinder. They feature proven cam and barrel skirt profiles, which help the piston move smoothly and reduce wear on your cylinder walls, even under aggressive use. The ring lands and grooves are machined to very strict standards, which is important for getting a good seal with your piston rings. A better ring seal means more consistent compression and ultimately, more power from your engine. These pistons also come with tool steel wrist pins, which are strong and durable, ensuring reliable operation.

For those looking to push their LS engine to the limit, Manley's unique manufacturing process 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 vital for optimal ring seal and performance. If you're a professional engine builder or a serious tuner looking for pistons that can handle demanding applications, these Manley pistons are a solid choice.
