What material are these pistons made from and why is it important?

These pistons are forged from domestic 2618 alloy. This material is chosen for its superior strength and ability to withstand the high stresses and temperatures found in performance engines, contributing to overall durability.

What is the purpose of the cam and barrel skirt profiles?

The cam and barrel skirt profiles are carefully shaped to optimize piston movement within the cylinder. This design helps to generate substantial power while also minimizing friction and wear on the cylinder walls, promoting a longer engine life.

Are any other wrist pin materials available?

While these pistons come standard with chrome moly wrist pins, Manley offers upgrades to 9310 and Turbo Tuff/DLC alloys on select part numbers for even greater durability in demanding applications.

About this part

Product Details

These Manley Performance pistons start with domestic 2618 alloy forgings, a material chosen for its exceptional strength and ability to handle high performance demands. They are specifically sized for a 4.600-inch bore with a 1.645-inch compression height and a -3.00cc dish, making them a solid choice for rebuilding or upgrading your Chevrolet big block engine.

Manley has put a lot of thought into the design of these pistons. They feature proven cam and barrel skirt profiles, which are shaped to generate significant power while also being gentle on your cylinder walls, reducing wear over time. The ring lands and grooves are machined to exacting standards, which is crucial for achieving a tight seal with your piston rings, ultimately leading to more efficient combustion and better power output. For added durability, these pistons come standard with chrome moly wrist pins, and Manley's unique fixturing process allows for skirt turning and ring groove machining in a single operation, ensuring the ultimate squareness between the ring grooves and the piston skirt.

When you're building a high-performance engine, the details matter. These pistons are a popular choice among professional engine builders and tuners who depend on Manley for reliable performance and durability. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. You'll also want to check the manufacturer's instructions for any specific installation requirements or recommended components for your build.
