What is the purpose of the -29cc dish in these pistons?

The -29cc dish is a feature that helps reduce the compression ratio of your engine. This is particularly useful in high-performance builds, especially those using forced induction like turbochargers or superchargers, as it helps prevent detonation.

What makes these pistons 'Extreme Duty'?

These pistons are considered 'Extreme Duty' due to their construction using strong 2618 alloy forgings and premium Chrome Moly wrist pins. This robust design allows them to withstand higher cylinder pressures and temperatures common in high-horsepower or racing applications.

Are these pistons compatible with all LS engine blocks?

These pistons are specifically designed for the Manley LS Series, which includes popular Chevy engines like the LS1, LS2, LS3, LS6, and LS7. While they share many characteristics, always confirm the specific bore size and dish volume match your engine block's requirements and your build goals.

About this part

Product Details

When you're rebuilding the top end of your Chevy LS engine for serious performance, the pistons are a critical component. These Manley Extreme Duty pistons are designed for LS1, LS2, LS3, LS6, and LS7 series engines, featuring a 4.08-inch bore and a -29cc dish to help achieve your desired compression ratio. They are built to handle the demands of high-horsepower applications, making them a solid choice for engine builders looking for reliability and power.

Manley uses domestic 2618 alloy forgings for these pistons, which are known for their strength and ability to withstand extreme conditions. They also come standard with premium Chrome Moly wrist pins, and Manley's unique fixturing process ensures the ring lands and skirt machining are perfectly square, which is essential for optimal ring seal and consistent power output. The cam and barrel skirt profiles are carefully designed to reduce friction and wear on your cylinder walls while still generating substantial power.

Because these are extreme duty pistons, they are often used in builds where forced induction or high RPMs are expected. It's important to note 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, especially when setting ring gaps and piston-to-wall clearance for your specific application.
