What material are these pistons made from?

These Manley "Platinum Series" pistons are forged from a domestic 2618 alloy. This material is chosen for its exceptional strength and performance characteristics, making it suitable for demanding engine builds.

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

The cam and barrel skirt profiles are carefully engineered shapes that help the piston move smoothly within the cylinder bore. This design reduces friction and wear on the cylinder walls while still allowing the piston to contribute to engine power.

Are these pistons suitable for all LS engine builds?

These pistons are designed for Small Block Chevy LS Series engines and feature a 4.030 inch bore and a -10cc dish. It's important to confirm that these specifications align with your specific engine build's requirements for compression ratio and bore size.

About this part

Product Details

When you're rebuilding the top end of your Small Block Chevy LS engine, especially if you're aiming for more power or durability, selecting the right pistons is crucial. These Manley "Platinum Series" pistons are built for serious performance, featuring a 4.030-inch bore size and a -10cc dish to help achieve your desired compression ratio. They are designed to handle the demands of performance builds, offering a solid foundation for your engine.

Manley uses domestic 2618 alloy forgings for these pistons, which are known for their strength and ability to perform under pressure. The pistons also come with chrome moly wrist pins, and Manley's signature cam and barrel skirt profiles are included. These profiles are carefully shaped to reduce friction and wear on your cylinder walls while still allowing the piston to generate power. Plus, the exacting standards for ring lands and grooves mean you'll get a better seal from your piston rings, which directly translates to more power and efficiency.

What sets these pistons apart is Manley's unique manufacturing process. Their fixturing 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, which is critical for optimal ring seal and overall engine health. If you're building a performance LS engine, these pistons are a well-built choice that professional engine builders trust for their projects.
