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

These Manley pistons are forged from domestic 2618 alloy. This material is chosen for its superior strength and performance characteristics compared to cast aluminum, making it ideal for high-output and demanding engine applications.

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 minimize wear on the cylinder walls while still allowing the piston to generate significant power.

Are these pistons compatible with all LS engine builds?

These pistons feature a 4.185-inch bore and a -20.00cc dish volume. While suitable for many performance LS builds, you should confirm these specifications match your engine's requirements and intended compression ratio.

About this part

Product Details

If you're building a high-performance Chevrolet LS engine, getting the right pistons is critical for power and reliability. This Manley Performance piston set is designed for serious builds where stock components just won't cut it. They feature a 4.185-inch bore and a -20.00cc dish volume, making them suitable for a wide range of performance applications, from naturally aspirated street builds to forced induction setups.

Manley uses domestic 2618 alloy forgings for these pistons, which offers superior strength compared to cast aluminum, essential for handling the increased pressures and temperatures of a performance engine. The pistons also feature proven cam and barrel skirt profiles that help reduce friction and wear on your cylinder walls while still generating substantial power. You'll find exacting standards applied to the ring lands and grooves, which is key for a good seal and maximizing the power your engine makes. Plus, Manley's unique machining process ensures the ring grooves are perfectly square to the skirt, contributing to overall engine health and performance.

This set includes premium chrome moly wrist pins, known for their durability. For those pushing the limits, Manley offers upgrades to even stronger alloys. Remember that these pistons are not CARB approved and cannot be shipped to California. They are a well-built component for anyone serious about their LS engine build.
