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

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

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 reduce friction and wear on the cylinder walls while still allowing the piston to generate substantial power.

Are these pistons compatible with all LS engines?

These pistons are specifically designed for Chevrolet LS engines with a 4.125 inch bore. While they are intended for performance builds, it's crucial to verify that the compression height and dish volume (-20.00cc) are suitable for your specific engine combination and desired compression ratio.

About this part

Product Details

If you're building a high-performance Chevrolet LS engine, this Manley Performance Piston Set is a solid choice for serious power. These pistons are designed for a 4.125-inch bore and feature a -20.00cc dish volume, with a 1.065-inch compression height. They're built to handle the demands of boosted or naturally aspirated performance builds where reliability and power are key.

Manley uses domestic 2618 alloy forgings for these pistons, which means they're incredibly strong and can withstand high cylinder pressures and temperatures. The pistons feature proven cam and barrel skirt profiles, designed to reduce friction and wear on your cylinder walls while still generating substantial power. You'll also find exacting standards in the ring lands and grooves, which helps ensure a better seal for improved performance. For added durability, these pistons come with tool steel wrist pins, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the piston skirts, which is critical for proper ring seal.

This set is intended for professional engine builders and tuners who need reliable components for their custom LS builds. Keep in mind that 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.
