What material are these pistons made from and why is it important?

These pistons are forged from domestic 2618 alloy. This material is chosen for its superior strength and ability to withstand the high temperatures and pressures found in performance LS engines, ensuring durability and reliable performance.

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

The cam and barrel profiles on the piston skirts are engineered to optimize power generation while minimizing friction and wear against the cylinder walls. This design helps ensure efficient engine operation and contributes to the longevity of your engine components.

Are these pistons compatible with all LS engines?

These pistons are designed for Chevrolet LS engines with a 4.185-inch bore. It is important to verify that this bore size and the -20.00cc dish volume are suitable for your specific engine build and desired compression ratio. They are not CARB approved and cannot be shipped to California.

About this part

Product Details

Manley Performance is well-known for building strong, reliable engine components that professional builders trust. If you're working on a high-performance Chevrolet LS engine build, this set of forged pistons is designed to handle the demands of serious power. They feature a 4.185-inch bore and a -20.00cc dish, which is a common configuration for many LS engine builds aiming for increased displacement and specific compression ratios.

These pistons are forged from domestic 2618 alloy, a material chosen for its exceptional strength and ability to withstand high temperatures and pressures without deforming. The cam and barrel skirt profiles are carefully shaped to help generate power efficiently while also being gentle on your cylinder walls, which contributes to longer engine life. Manley also pays close attention to the details, ensuring the ring lands and grooves are machined to exacting standards. This precise machining is crucial for achieving a solid ring seal, which directly translates to better compression and more power from your engine.

Included with these pistons are premium chrome moly wrist pins, known for their durability. For those pushing the limits even further, Manley offers upgrades to even tougher alloys. The unique fixturing Manley uses allows them to machine the skirt and cut the ring grooves in one operation. This ensures the ring grooves are perfectly square to the piston skirt, which is another key factor in achieving optimal ring seal and overall engine performance. These pistons are a solid choice for anyone rebuilding or upgrading their LS engine and looking for components that offer both performance and longevity.
