What is the purpose of the -11.5cc dish in these pistons?

The -11.5cc dish is a volume machined into the top of the piston. It helps to lower the overall compression ratio of your engine, which is often necessary when using a longer stroke crankshaft or when planning to use forced induction like a turbocharger or supercharger.

What are the benefits of using 2618 alloy forgings?

2618 alloy is a popular choice for high-performance pistons because it offers excellent strength and ductility. This means it can handle high cylinder pressures and temperatures without fracturing, while also having some flexibility to prevent cracking under extreme stress.

Are any special tools or procedures needed for installing these pistons?

While these pistons are designed for a direct fit in the specified bore size, installing performance pistons typically requires specialized engine building knowledge and tools. Always refer to Manley's official installation instructions or consult a professional engine builder for proper assembly and break-in procedures.

About this part

Product Details

When you're building a high-performance 6.1L Hemi engine, especially one designed for increased displacement or forced induction, the pistons are a critical component. This Manley Stroker Series piston set is crafted to handle the demands of a stroker build, offering a solid foundation for serious power. The -11.5cc dish helps achieve your target compression ratio when combined with your chosen cylinder heads and crankshaft.

These pistons are forged from domestic 2618 alloy, a material known for its exceptional strength and ability to withstand high cylinder pressures and temperatures. Manley machines them with proven cam and barrel skirt profiles, which help reduce friction and wear on your cylinder walls while still generating significant power. The ring lands and grooves are machined to exacting standards, ensuring a tight seal for improved combustion efficiency and power output. Each set includes premium chrome moly wrist pins, and Manley's unique manufacturing process ensures the ring grooves are perfectly square to the piston skirt for optimal performance.

This piston set is designed for a 4.060-inch bore and is compatible with a 6.240-inch rod length. Remember that these pistons are not CARB approved and cannot be shipped to California. For a build of this caliber, it's always recommended to consult with your engine builder or refer to Manley's installation guidelines for specific details on assembly and break-in procedures.
