What material are these pistons made from?

These Manley pistons are forged from domestic 2618 alloy. This material is chosen for its exceptional strength and ability to handle the high stresses and temperatures of performance engine builds.

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 bore. They help reduce friction and wear while 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 4.005-inch bore. While many LS engines share commonalities, it's important to verify your specific engine's bore size and build requirements before purchasing.

About this part

Product Details

If you're building a high-performance Chevrolet LS engine, getting the right pistons is crucial for power and reliability. This set from Manley Performance is designed for builders who demand strength and precision. They feature a 4.005-inch bore and a -29.00cc dish, which is a common configuration for naturally aspirated or boosted LS applications where specific compression ratios are targeted.

Manley uses domestic 2618 alloy forgings for these pistons, a material known for its exceptional strength and ability to withstand the high pressures and temperatures found in performance engines. The pistons also come with proven cam and barrel skirt profiles, which help them operate smoothly against the cylinder walls, reducing friction and wear while still generating substantial power. You'll also find exacting standards applied to the ring lands and grooves, which is key for achieving a solid ring seal and maximizing the power your engine makes. These pistons include chrome moly wrist pins, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the skirt for optimal performance.

This set is a popular choice among professional engine builders for its well-built nature and the performance gains they can achieve. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a complete build, ensure you have the correct supporting components like rings, connecting rods, and a balanced crankshaft.
