What material are these pistons made from?

These Manley pistons are forged from a domestic 2618 alloy. This material is chosen for its superior strength and performance characteristics, making it well-suited for high-stress engine applications.

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

The cam and barrel skirt profiles are designed to help the piston run true and quiet within the cylinder bore. This design helps to minimize noise and wear on the cylinder walls while still maintaining excellent performance.

Are these pistons suitable for all LS engine builds?

These pistons are designed for Chevrolet LS engines and feature a 4.185-inch bore and a -29.00 CC dish, which affects compression ratio. It's important to ensure these specifications match your specific engine build goals and other components, such as cylinder heads and camshaft.

About this part

Product Details

When you're building a high-performance Chevrolet LS engine, the pistons are a critical component that needs to handle serious stress. This Manley Performance piston set is designed for just that, using a robust 2618 alloy forging that's known for its strength and ability to withstand high cylinder pressures and temperatures. The 4.185-inch bore size and -29.00 CC dish help achieve a specific compression ratio, making them suitable for many performance applications where you need more power than stock.

Manley uses proven cam and barrel skirt profiles on these pistons. This design helps them run true and quiet in the cylinder bore while still allowing for excellent ring seal. Speaking of rings, the ring lands and grooves are machined to very tight tolerances, which is essential for getting the best possible seal from your piston rings. This means more power getting to the crankshaft and less blow-by. The included chrome moly wrist pins are strong and durable, ready for the demands of a performance engine. For those pushing the limits, Manley's unique machining process ensures the ring grooves are perfectly square to the piston skirt, which is a detail that matters for long-term reliability and performance.

This set is a solid choice for engine builders looking for well-made, forged pistons that can handle boosted or naturally aspirated performance 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.
