What is the main advantage of using forged pistons like these?

Forged pistons are significantly stronger and more durable than cast pistons. This makes them ideal for high-performance applications where engines experience higher cylinder pressures and temperatures.

What does the -18.00 CC dish volume mean for my engine?

The CC volume refers to the shape of the piston top. A dish volume like -18.00 CC removes volume from the combustion chamber, which will lower your overall compression ratio. This is important to consider when selecting cylinder heads to achieve your target compression.

Are these pistons coated?

Select Manley piston part numbers feature moly skirt coatings for added durability. This specific part number, 596280C-8, includes Chrome Moly wrist pins and is forged from 2618 alloy with precise ring lands and skirt profiles.

About this part

Product Details

If you're building a high-performance Chevrolet LS engine, this Manley Piston Set is a solid choice for serious power. These are forged pistons, meaning they start as a solid block of aluminum that's heated and hammered into shape. This process makes them much stronger and more durable than cast pistons, which is essential when you're pushing an engine hard. The specific alloy used here is a domestic 2618, known for its excellent strength and performance characteristics under high stress.

Manley has put a lot of thought into the design of these pistons. They feature proven cam and barrel skirt profiles, which help the piston move smoothly in the cylinder bore. This design not only helps generate more power but also reduces wear on your cylinder walls, extending the life of your engine build. The ring lands and grooves are machined to very strict standards, which is critical for getting a good seal with your piston rings. A tight seal means better compression and more power, while also preventing oil from getting into the combustion chamber.

Included with this set are premium Chrome Moly wrist pins, which are strong and reliable. Manley's unique manufacturing process allows them to machine the skirt and the ring grooves in one operation. This ensures that the ring grooves are perfectly square to the piston skirt, which further improves the ring seal and overall engine performance. These pistons are designed for a 4.080-inch bore and have a compression height of 1.115 inches, with a -18.00 CC dish volume, which will affect your final compression ratio depending on your cylinder head volume.
