What is the primary benefit of using 2618 alloy forgings?

2618 alloy forgings are used because they offer superior strength and performance compared to other materials. This makes them ideal for high-output and demanding engine applications where durability is critical.

What does the -20.00cc dish volume signify?

The -20.00cc dish volume refers to the shape and depth of the piston's crown. This specification is crucial for calculating and achieving the desired compression ratio when paired with specific cylinder heads and head gaskets.

Are these pistons coated?

Select Manley piston part numbers feature moly skirt coatings for added durability and reduced friction. Please check the specific product details for this part number to confirm if skirt coating is included.

About this part

Product Details

Built from domestic 2618 alloy forgings, these Manley pistons are designed for serious performance builds in Chevrolet LS engines. The 4.130-inch bore size and -20.00cc dish volume are key specifications for achieving specific compression ratios in modified LS applications. Manley's commitment to precision is evident in their exacting standards for ring lands and grooves, which directly contribute to better ring seal and ultimately, more power from your engine.

You'll find that Manley has incorporated proven cam and barrel skirt profiles into these pistons. This design choice is important because it helps generate substantial power gains while also being gentle on your cylinder walls, leading to longer engine life. The unique fixturing Manley uses allows them to machine the skirt and ring grooves in a single operation, ensuring ultimate squareness between these critical areas. This level of attention to detail is why professional engine builders trust Manley for their high-performance projects.

This set includes premium chrome moly wrist pins, which are a strong standard for durability. For those pushing the limits, Manley offers upgrades to even tougher alloys. When you're rebuilding or modifying your LS engine for maximum output, these pistons offer a well-built foundation that can handle the demands of performance tuning and racing.
