What material are these pistons made from?

These Manley Platinum Series pistons are forged from domestic 2618 alloy. This material is chosen for its superior strength and performance characteristics, especially under high-stress conditions.

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

The cam and barrel (skirt) profiles on these pistons are engineered to reduce friction and wear on the cylinder walls. This design helps ensure a longer engine life while still allowing the piston to contribute to substantial power output.

Are these pistons compatible with all LS engines?

These pistons are designed for Small Block Chevy LS Series engines with a 4.075-inch bore and an -18cc dish. It's important to verify that these specifications match your specific engine build and intended compression ratio.

About this part

Product Details

If you're rebuilding the heart of your Small Block Chevy LS engine and aiming for serious performance, these Manley Platinum Series pistons are a solid choice. They're built to handle the demands of a high-performance build, offering a significant step up from stock components. With a 4.075-inch bore and an -18cc dish volume, they're designed for specific compression ratios and engine configurations.

Manley uses domestic 2618 alloy forgings for these pistons, which are known for their strength and ability to withstand high temperatures and pressures. The cam and barrel skirt profiles are carefully shaped to reduce friction and wear on your cylinder walls while still generating substantial power. You'll also find exacting standards in the ring lands and grooves, which are crucial for a good seal and maximizing the power your engine makes. Plus, they come standard with premium chrome moly wrist pins, and Manley's unique fixturing ensures the ring grooves are perfectly square to the skirt for optimal performance.

These pistons are a popular choice among professional engine builders for good reason. They represent a well-built component that can be a cornerstone of a reliable, powerful engine build. Keep in mind that these are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
