What material are these pistons made from?

These Manley pistons are forged from a domestic 2618 alloy. This material is chosen for its strength and ability to perform under the stresses of a high-performance engine build.

What is the dish volume and why does it matter?

The pistons have a -2.00cc dish volume. This dish is part of the combustion chamber design and helps determine the final compression ratio of your engine, which is critical for performance tuning.

Are these pistons compatible with all piston rings?

Manley adheres to strict standards for piston ring lands and grooves. This precise machining ensures enhanced ring seal and compatibility with high-performance piston ring sets.

About this part

Product Details

If you're building a high-performance Chevrolet LT1 engine, this Manley 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 demands of a performance build. The bore size is 4.080 inches, and the compression height is 1.304 inches, with a -2.00cc dish volume to help achieve your desired compression ratio.

Manley puts a lot of thought into their piston design. They use proven cam and barrel skirt profiles that help generate power while also being easier on your cylinder walls. The ring lands and grooves are machined to very strict standards, which is crucial for getting a good seal from your piston rings and ultimately making more power. They even use unique fixturing so they can machine the skirt and ring grooves in the same operation, ensuring they are perfectly square to each other. This set includes premium chrome moly wrist pins, and for some part numbers, Manley offers upgrades to even stronger alloys like 9310 or Turbo Tuff/DLC for added durability.

This set is designed for serious engine builders and tuners looking for reliable performance. 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.
