What material are these pistons made from?

These Manley Platinum Extreme Duty pistons are forged from domestic 2618 alloy. This material is known for its superior strength and durability, making it ideal for high-performance engine builds.

What is the purpose of the -20cc dish in these pistons?

The -20cc dish is a feature that helps to control the engine's compression ratio. It's often used in performance applications to lower compression, which can be beneficial for forced induction setups or specific camshaft profiles.

Are these pistons compatible with all LS engines?

These pistons are designed for LS engines with a specific 4.070 inch bore. While they are for the LS family, you must confirm this bore size matches your engine's requirements. They are not CARB approved and cannot ship to California.

About this part

Product Details

If you're building a high-performance Chevy LS engine, these Manley Platinum Extreme Duty pistons are a solid choice. They're designed for a 4.070-inch bore and feature a -20cc dish, making them suitable for various performance applications where you need to control compression ratio. Manley is a well-known name in racing and performance engine building, and these pistons are built to handle serious power.

What sets these pistons apart is the material: they're forged from domestic 2618 alloy. This material is chosen for its exceptional strength and durability, which is crucial when you're pushing an engine hard. They also come with premium chrome moly wrist pins, and Manley pays close attention to the precision of the ring lands and grooves. This exacting work ensures a better seal from your piston rings, which translates directly into more power and better efficiency. The cam and barrel skirt profiles are also carefully designed to reduce friction and wear on your cylinder walls, even under high loads.

Manley uses a unique fixturing process that allows them to machine the skirt and the ring grooves in one setup. This ensures that the ring grooves are perfectly square to the piston skirt, which is another detail that contributes to a superior ring seal and overall engine performance. These are a set of 8 pistons, ready for your next LS engine build. Keep in mind that these are not CARB approved and cannot be shipped to California.
