What is the purpose of the 2618 alloy forging?

The 2618 alloy is chosen for its superior strength and ability to withstand high temperatures and pressures. This makes it ideal for performance engine builds where pistons are subjected to significant stress.

What is the significance of the -18.00cc dish volume?

The dish volume directly impacts the engine's compression ratio. A -18.00cc dish will lower the compression ratio compared to a flat-top or domed piston, which is often desired for forced induction applications or specific engine tuning goals.

Are these pistons compatible with all LS engine blocks?

These pistons are designed for Chevrolet LS engines with a 3.905 inch bore. Compatibility with specific LS engine blocks depends on the block's bore size and the overall engine build strategy, including cylinder head volume and gasket thickness.

About this part

Product Details

When you're building a high-performance Chevrolet LS engine, the pistons are a critical component that needs to handle significant stress. This Manley Piston Set is designed for builders who demand reliability and power from their engine builds. They are forged from a 2618 alloy, a material known for its strength and ability to withstand the high temperatures and pressures found in performance applications.

Manley has incorporated proven cam and barrel skirt profiles into these pistons. This design helps manage piston slap and reduces wear on your cylinder walls, even under aggressive use. The ring lands and grooves are machined to very strict standards, which is essential for achieving a good seal with your piston rings. A solid ring seal means better compression and more power from your engine. These pistons also come with tool steel wrist pins, which are strong enough for most performance builds, and feature a moly skirt coating on this specific part number to further reduce friction and improve durability.

This set is intended for engine builders who are looking to push the limits of their LS engine. The -18.00cc dish volume is a specific design choice that affects compression ratio, so be sure to factor this into your overall engine build calculations. Remember 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.
