What material are these pistons made from and why is it important?

These pistons are forged from a domestic 2618 alloy. This material is chosen for its exceptional strength and ability to withstand the high stresses and temperatures found in performance LS engines, ensuring both power and durability.

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 generate more power while also reducing friction and wear on the cylinder walls, contributing to a longer engine life.

Are these pistons compatible with all LS engine builds?

These pistons are specifically designed for Chevrolet LS engines with a 4.070-inch bore and a -31.00 CC dish. While they offer excellent performance, it's essential to ensure these specifications match your engine's requirements and desired compression ratio. They are not CARB approved and cannot be shipped to California.

About this part

Product Details

If you're rebuilding the heart of your Chevrolet LS engine, choosing the right pistons is critical for both power and longevity. These Manley Performance pistons are forged from a domestic 2618 alloy, a material known for its exceptional strength and ability to handle high performance demands. They are designed with proven cam and barrel skirt profiles, which help generate substantial power while minimizing wear on your cylinder walls.

Manley takes precision seriously. They maintain strict standards for the ring lands and grooves, ensuring a better seal for your piston rings, which translates directly into more power. Their unique fixturing process allows them to machine the skirt and cut the ring grooves in one operation. This ensures the ring grooves are perfectly square to the piston skirt, further enhancing the seal and overall performance. These pistons come with tool steel wrist pins, and for some part numbers, upgrades to 9310 or Turbo Tuff/DLC alloys are available for even greater durability.

This set features a 4.070-inch bore size and a -31.00 CC dish volume, which is important for achieving your desired compression ratio. Remember, 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 procedures.
