What material are these pistons made from?

These Manley Platinum Series pistons are forged from domestic 2618 alloy. This material is chosen for its exceptional strength and performance under high-stress conditions common in performance Hemi engines.

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 bore. This design helps to reduce friction and wear on the cylinder walls while contributing to improved power output.

Are these pistons suitable for all Hemi engine builds?

These pistons are designed for performance applications and feature specific bore, stroke, and compression height dimensions. It's important to confirm these specifications match your intended engine build and that the pistons are compatible with your chosen cylinder heads and crankshaft.

About this part

Product Details

If you're rebuilding a Dodge Hemi engine for serious performance, a strong set of pistons is where you start. These Manley Platinum Series pistons are built to handle the demands of high-output Hemi engines, whether you're building a street machine or a track-focused race motor. They feature a 3.937-inch bore and a 4.050-inch stroke, with a 1.085-inch compression height, making them a solid choice for many 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 have proven cam and barrel skirt profiles designed to work smoothly with cylinder walls, reducing friction and wear while helping to generate more power. The ring lands and grooves are machined to strict standards to ensure a good seal with your piston rings, which is crucial for both power and oil control. Each set also includes premium chrome moly wrist pins for added durability.

For builders looking for the best, Manley's unique fixturing process allows them to machine the skirt and cut the ring grooves in a single operation. This ensures the ring grooves are perfectly square to the piston skirt, contributing to a more reliable seal under stress. These pistons are a popular choice among professional engine builders and tuners who need reliable components for their performance projects.
