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 handle the high pressures and temperatures found in performance engines, making them ideal for demanding builds.

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

The cam and barrel profiles on the piston skirts are designed to manage piston movement within the cylinder. This helps to reduce wear on the cylinder walls while still allowing the piston to generate substantial power efficiently.

Are these pistons compatible with all Chevy LT1 engines?

These pistons are specifically designed for Chevy LT1 engines that utilize Direct Injection. It is important to confirm that your engine uses direct injection and that the 4.070-inch bore size and -12cc dish volume are appropriate for your intended build before purchasing.

About this part

Product Details

Manley Performance is well-known for building robust engine components, and their Direct Injected Series pistons are a prime example of that commitment. If you're working on a Chevy LT1 engine that uses direct injection and you're looking to build serious power, these pistons are designed to handle the demands. They feature a 4.070-inch bore and a -12cc dish, making them suitable for specific compression ratio targets in performance builds.

These pistons are forged from domestic 2618 alloy, a material chosen for its exceptional strength and ability to withstand high cylinder pressures and temperatures. Manley uses proven cam and barrel skirt profiles that help manage piston rock, reducing wear on your cylinder walls while still generating substantial power. The ring lands and grooves are machined to exacting standards, which is crucial for achieving a tight seal with your piston rings. This improved ring seal means better combustion efficiency and more power getting to the crankshaft. For added durability, these pistons come standard with premium Chrome Moly wrist pins.

Manley's unique fixturing process allows them to machine the piston skirt and its ring grooves in a single operation. This ensures that the ring grooves are perfectly square to the piston skirt, which is vital for optimal ring seal and overall engine performance. While these pistons are built for extreme duty, please note they are not CARB approved and cannot be shipped to California. They are designed for performance applications where durability and strength are paramount.
