What material are these pistons made from?

These Manley pistons are forged from domestic 2618 alloy. This material is chosen for its superior strength and ability to perform under high stress and temperature conditions common in performance engines.

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

The cam and barrel profiles on the piston skirts are designed to optimize the piston's movement within the cylinder. This design helps to reduce friction and wear on the cylinder walls while still allowing the piston to contribute to significant power output.

Are piston rings included with this set?

Piston rings are not included with this piston set. You will need to purchase compatible piston rings separately to complete your engine assembly. It is recommended to use rings specifically designed for forged pistons and your engine's bore size.

About this part

Product Details

If you're rebuilding a Chevrolet LS engine and looking for a solid set of pistons, this Manley Performance set is a popular choice among professional builders. These are forged pistons designed for high-performance applications, meaning they can handle more stress and power than cast pistons. The 4.070-inch bore size is a common upgrade for LS engines, and the -29.00 CC dish volume helps achieve a specific compression ratio when paired with the right cylinder heads and crankshaft.

Manley uses domestic 2618 alloy forgings for these pistons, which are known for their strength and ability to withstand high temperatures and pressures. They also feature proven cam and barrel skirt profiles, which help reduce friction and wear on your cylinder walls while still allowing the piston to generate substantial power. The ring lands and grooves are machined to exacting standards, ensuring a good seal with your piston rings for improved power and efficiency. These pistons come with premium chrome moly wrist pins, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the skirt for optimal performance.

This piston set is designed for serious engine builds. It's important to note that these are not CARB approved and cannot be shipped to California. You'll want to ensure you have the correct supporting components, like matching piston rings and connecting rods, to complete your engine assembly. Refer to the manufacturer's installation instructions for detailed specifications and assembly procedures.
