What makes these pistons 'Extreme Duty'?

These pistons are considered 'Extreme Duty' due to their construction from high-strength 2618 alloy forgings and the inclusion of durable Chrome Moly wrist pins. This robust design is intended to handle the increased stresses of high-performance engine builds.

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. This helps to reduce friction and wear on the cylinder walls while still allowing the piston to effectively transfer power.

Are piston rings included with this set?

This listing is for the piston set only. Piston rings and wrist pin clips are typically sold separately and should be chosen based on your specific engine build requirements.

About this part

Product Details

If you're building a high-performance Chrysler 6.1L Hemi engine, you need pistons that can handle the stress. These Extreme Duty pistons from Manley are forged from domestic 2618 alloy, a material known for its exceptional strength and ability to withstand high cylinder pressures and temperatures. They feature a -11.5cc dish, a 4.065-inch bore, and a 3.579-inch stroke, making them a solid choice for serious engine builds.

Manley uses proven cam and barrel skirt profiles on these pistons. This design helps reduce friction and wear on your cylinder walls while still allowing the piston to generate substantial power. The ring lands and grooves are machined to exacting standards, which is crucial for achieving a tight seal with your piston rings. This improved ring seal means more consistent compression and better overall engine performance. Each set also includes premium Chrome Moly wrist pins for added durability, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the piston skirt for optimal performance.

These pistons are a popular choice among professional engine builders and tuners who demand reliability and performance. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a complete build, you'll want to ensure you have the correct supporting components like rings, connecting rods, and a quality machine shop to prepare your block and crankshaft.
