What is the purpose of the -1.5cc flat top dish on these pistons?

The -1.5cc flat top dish is a specific design feature that helps control the compression ratio when used with certain cylinder heads. This allows engine builders to fine-tune the engine's compression for optimal performance based on their build goals.

What are the benefits of using 2618 alloy forgings?

2618 alloy is chosen for its excellent strength and toughness, especially at higher temperatures. This makes it ideal for high-performance applications where pistons experience significant stress and heat, contributing to overall engine durability.

Are these pistons compatible with all 6.1L Hemi engines?

These pistons are designed for the 6.1L Hemi engine with a 4.065-inch bore. It is crucial to verify that this bore size and piston dish specification match your specific engine build and intended compression ratio.

About this part

Product Details

Manley Performance is well-known for building strong, reliable engine components that professional builders trust. This Stroker Series piston set is designed for Chrysler 6.1L Hemi engines, featuring a 4.065-inch bore and a -1.5cc flat top dish. These pistons are a key part of building a larger displacement engine, often referred to as a stroker build, which can significantly increase torque and horsepower.

These pistons are forged from domestic 2618 alloy, a material chosen for its exceptional strength and performance under high stress. They feature proven cam and barrel skirt profiles, which help generate power efficiently while also being gentle on your cylinder walls during operation. Manley also pays close attention to the details, adhering to strict standards for the ring lands and grooves. This exacting machining ensures a better ring seal, which translates directly to more power and improved efficiency. The set includes premium chrome moly wrist pins, known for their durability.

When building a high-performance engine, the quality of internal components like pistons is critical. Manley's unique fixturing process allows them to machine the skirt and ring grooves in a single operation. This ensures the ring grooves are perfectly square to the skirt, which is essential for optimal ring seal and engine longevity. Please note that these pistons are not CARB approved and cannot be shipped to California.
