What is included in this piston set?

This set includes the pistons, tool steel wrist pins, and wrist pin locks. You will need to source your own piston rings separately, sized appropriately for your build.

What is the purpose of the -31.00 CC dish?

The -31.00 CC dish is a specific volume machined into the piston crown. This volume affects the combustion chamber size, which directly impacts your engine's compression ratio. It's a key specification for tuning performance engines.

Are these pistons suitable for a street-driven car?

These pistons are built for high performance and durability, often used in racing or heavily modified street applications. They are not CARB approved and cannot be shipped to California, indicating they are intended for off-road or competition use where emissions regulations differ.

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. Designed for a 4.075-inch bore, these pistons feature a -31.00 CC dish, which is crucial for setting your compression ratio. Manley is a well-known name among professional engine builders for a reason – their parts are built to handle the demands of performance applications.

These pistons are forged from 2618 alloy, a strong material that holds up well under high cylinder pressures and temperatures. They come with tool steel wrist pins, and Manley uses a unique process that ensures the ring lands and grooves are machined with great accuracy. This attention to detail helps achieve a better seal with your piston rings, which translates directly into more power. The cam and barrel skirt profiles are also designed to be effective at generating power while minimizing wear on your cylinder walls.

This set includes pistons, wrist pins, and locks. Keep in mind 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.
