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 ability to handle the high pressures and temperatures found in performance and racing engines.

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

Are these pistons suitable for all LS engine builds?

These pistons have a specific bore size (4.135 inches), compression height (1.065 inches), and dish volume (-20.00cc). They are intended for modified LS engines where these specifications align with the desired compression ratio and overall engine combination. Always confirm compatibility with your engine builder or specifications.

About this part

Product Details

If you're rebuilding the heart of your Chevrolet LS engine for serious performance, a strong set of pistons is where you start. This Manley Piston Set is built for those demanding builds where reliability and power are paramount. They feature a 4.135-inch bore size, a 1.065-inch compression height, and a -20.00cc dish volume, making them suitable for specific compression ratio targets in modified LS engines.

Manley uses domestic 2618 alloy forgings for these pistons, a material known for its exceptional strength and ability to withstand high cylinder pressures and temperatures. This is crucial for engines that will see track use or aggressive street driving. The pistons also feature proven cam and barrel skirt profiles, which help reduce friction and wear on your cylinder walls 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. For added durability, these pistons come standard with premium chrome moly wrist pins.

Manley's unique manufacturing process allows them to machine the skirt and ring grooves in a single operation. This ensures the ring grooves are perfectly square to the piston skirt, which further contributes to a better ring seal and overall engine performance. These pistons are a solid choice for professional engine builders and tuners looking for reliable components for their high-performance LS builds.
