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 capabilities, especially under high-temperature and high-pressure conditions common 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. This helps to generate substantial power while also minimizing wear on the cylinder walls, contributing to longer engine life.

Are these pistons compatible with all LS engines?

These pistons are specifically designed for Chevrolet LS engines with a 4.075-inch bore. It is important to verify your specific engine's bore size and requirements to ensure proper fitment, as well as checking the compression height and valve relief volume.

About this part

Product Details

If you're building a high-performance Chevrolet LS engine, this Manley Piston Set is a solid choice. These pistons are designed for a 4.075-inch bore and feature a 1.115-inch compression height with a -4.00cc valve relief. Manley is a well-known name in performance engine building, and these pistons are built to handle serious power.

Manley uses domestic 2618 alloy forgings, which are known for their strength and ability to withstand high temperatures and pressures. The pistons have proven cam and barrel skirt profiles, which help them generate power efficiently while also being gentle on your cylinder walls. This design contributes to improved ring seal, and Manley adheres to strict standards for their ring lands and grooves to ensure optimal performance. The unique fixturing Manley uses allows them to machine the skirt and ring grooves in one operation, ensuring they are perfectly square to each other for the best possible seal.

This set includes premium Chrome Moly wrist pins, which are built for durability. For those looking for even more robustness, Manley offers upgrades to 9310 and Turbo Tuff/DLC alloys on select part numbers. These pistons are a popular choice among professional engine builders and tuners who demand reliable performance from their LS engines. Please note that these pistons are not CARB approved and cannot be shipped to California.
