Manley Chrysler Hemi 6.1L 4.060in Bore -11.5cc Dish 1.220in CD Platinum Series Piston Set - ED

When you're rebuilding the top end of a Chrysler Hemi 6.1L engine, especially for a performance build, the pistons are a critical component. These Manley Platinum Series pistons are designed to handle the demands of a high-output Hemi, offering a solid foundation for serious engine work. They feature a -11.5cc dish, a 4.060-inch bore, and a 1.220-inch compression distance, making them suitable for specific compression ratio targets in performance applications.

Manley uses domestic 2618 alloy forgings for these pistons, which are known for their strength and ability to perform under high stress. The pistons also come with premium chrome moly wrist pins, and Manley's signature cam and barrel skirt profiles are included to help reduce friction and wear on the cylinder walls while still generating power. They also pay close attention to the ring lands and grooves, ensuring a tight seal for improved combustion efficiency and more power. The unique fixturing Manley uses allows them to machine the skirt and ring grooves in one operation, which helps ensure the squareness between these critical areas for optimal performance.

This set is designed for engine builders and tuners who rely on well-built components for their projects. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a successful build, always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
