What is the compression height (CH) of these pistons?

These Manley pistons have a compression height of 1.115 inches. This measurement is taken from the center of the wrist pin bore to the top of the piston crown and is crucial for setting your engine's deck height.

What is the dish volume and why does it matter?

The pistons feature a -29.00cc dish volume. This dish is a recessed area on the piston crown that affects your engine's static compression ratio when paired with your cylinder heads and block.

Are these pistons compatible with all LS engines?

These pistons are designed for LS engines with a 4.065-inch bore. While they are built for the LS platform, you must ensure this bore size and the compression height are correct for your specific engine build and cylinder heads.

About this part

Product Details

Manley's 592865CE-8 piston set starts with domestic 2618 alloy forgings, a material chosen for its exceptional strength and ability to handle high performance demands. These pistons are specifically designed for Chevrolet LS engines and feature a 4.065-inch bore with a -29.00cc dish, which is important for setting your compression ratio. The 1.115-inch compression height (CH) is also critical for achieving the correct deck height and valve-to-piston clearance.

You'll find that Manley pays close attention to the details that make a difference in engine building. The cam and barrel skirt profiles are engineered to help generate power while also being gentle on your cylinder walls, reducing wear over time. They also maintain exacting standards for the ring lands and grooves, which is key for a good seal and maximizing the power your engine makes. Each set includes tool steel wrist pins, and for select applications, Manley offers upgrades to even more durable alloys like 9310 and Turbo Tuff/DLC. Their unique fixturing process allows them to machine the skirt and ring grooves in one operation, ensuring the ring grooves are perfectly square to the skirt for optimal performance.

This piston set is a solid choice for anyone building a performance LS engine, whether you're a professional tuner or a dedicated enthusiast. They are built to withstand the rigors of performance use, offering both the strength and the precise dimensions needed for a well-built engine. 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.
