Manley Chrysler 6.1L Hemi 4.060in Bore 1.220in CD -1.5cc Flat Top Extreme Stroker Piston - Set of 8

When you're building a serious Hemi engine, you need pistons that can handle the stress and deliver consistent power. This set from Manley Performance includes eight forged pistons designed specifically for Chrysler 6.1L Hemi applications with a 4.060-inch bore. These aren't just any pistons; they're part of Manley's signature "Platinum Series," built for those who demand top-tier performance and durability from their engine components.

Manley uses domestic 2618 alloy forgings for these pistons, a material known for its exceptional strength, which is crucial for high-performance engines. They feature proven cam and barrel skirt profiles that help generate power while also being designed to be gentle on your cylinder walls, reducing wear over time. The ring lands and grooves are machined to exacting standards, which is key for achieving a solid ring seal and maximizing the power your engine makes. Each set also comes standard with tool steel wrist pins, offering robust support for the piston assembly.

For those pushing the limits, Manley's unique fixturing process allows for skirt turning and ring groove machining in a single operation. This ensures ultimate squareness between the ring grooves and the piston skirt, contributing to better performance and longevity. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. If you're aiming for serious power and reliability in your Hemi build, these Manley pistons are a well-built choice.
