What is the advantage of using forged pistons like these?

Forged pistons are made from a solid block of alloy that is heated and pressed into shape. This process creates a stronger, more durable piston that can withstand higher cylinder pressures and temperatures compared to cast pistons, making them ideal for performance and racing applications.

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

The dish in the piston crown affects the compression ratio of your engine. A -11.5cc dish typically lowers the compression ratio, which can be beneficial for forced induction (turbocharged or supercharged) applications or for engines designed to run on lower octane fuel.

What else might I need to complete an engine build with these pistons?

When installing these pistons, you will need to purchase a compatible set of piston rings, connecting rods, rod bearings, main bearings, and potentially a new oil pump and timing set. Always refer to your engine's service manual or a professional engine builder for a complete parts list.

About this part

Product Details

If you're rebuilding the heart of your Chrysler Hemi 6.1L, a solid set of pistons is where you start. This Platinum Series piston set from Manley is built for serious performance, designed to handle the demands of a high-output engine. They feature a 4.080-inch bore and a -11.5cc dish, which is a common configuration for naturally aspirated or boosted Hemi builds.

Manley uses domestic 2618 alloy forgings for these pistons, which are known for their strength and ability to withstand high temperatures and pressures. The pistons are also treated with proven cam and barrel skirt profiles that help reduce friction and wear on your cylinder walls, while still generating power. You'll also find exacting standards for the ring lands and grooves, which is crucial for a good seal and maximizing the power your engine makes. These pistons come standard with premium chrome moly wrist pins, and Manley's unique machining process ensures the ring grooves are perfectly square to the skirt for optimal performance.

This set is a popular choice among professional engine builders and tuners for good reason. They are well-built and designed to perform. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. You'll want to ensure you have the correct ring set and connecting rods to match the piston dimensions for a successful build.
