What material are these pistons made from?

These pistons are forged from a domestic 2618 alloy. This material is chosen for its superior strength and performance characteristics, making it well-suited for demanding engine builds.

What is the dish volume and why does it matter?

The dish volume on these pistons is -4.00cc. This specification is important for calculating your engine's final compression ratio when paired with specific cylinder heads and head gasket thickness.

Are these pistons compatible with all piston rings?

These pistons feature exacting ring lands and grooves, designed for enhanced ring seal. While they are designed to work with standard ring sets, it's always best to consult the manufacturer's recommendations or your engine builder for specific ring compatibility.

About this part

Product Details

If you're building a high-performance Chevrolet small block engine, Manley's Platinum Series piston set is a solid choice. These pistons are forged from a domestic 2618 alloy, which is known for its strength and ability to handle the stresses of performance applications. The set is designed for a 4.035-inch bore with a -4.00cc dish, meaning they will work with a variety of cylinder head combinations to achieve your desired compression ratio.

Manley puts a lot of thought into the details that make a difference. These pistons feature proven cam and barrel skirt profiles, which help them generate power efficiently while also being gentle on your cylinder walls. The ring lands and grooves are machined to strict standards to ensure a good seal with your piston rings, which is crucial for making maximum power. They also use tool steel wrist pins for added durability, and some part numbers even offer upgrades to even tougher alloys like 9310 or Turbo Tuff/DLC for extreme builds. Manley's unique fixturing process allows them to machine the skirt and ring grooves in one operation, ensuring they are perfectly square to each other.

This piston set is a popular choice among professional engine builders and tuners who need reliable components for their builds. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
