Manley Chevrolet LS Piston Set - 4.165in Bore 1.115in CH, -29.00 CC

This set includes eight forged pistons, each with a 4.165-inch bore and a 1.115-inch compression height. They feature a -29.00cc dish volume, which is important for setting your compression ratio. Manley uses domestic 2618 alloy forgings for these pistons, known for their strength and ability to handle high performance demands. This material choice is key for building a robust engine that can withstand significant stress.

You'll also find that these pistons come standard with tool steel wrist pins, offering good durability for demanding builds. The ring lands and grooves are machined to strict standards, which helps ensure a better seal from your piston rings, ultimately leading to more power. Manley's signature cam and barrel skirt profiles are designed to help the engine make substantial power while also being considerate of your cylinder walls during operation. They use a unique fixturing process that allows them to machine the skirt and ring grooves in one setup, ensuring the ring grooves are perfectly square to the piston skirt for optimal sealing.

If you're building a high-performance Chevrolet LS engine, these pistons are a solid option. Keep in mind that these are not CARB approved and cannot be shipped to California. For installation, you'll want to refer to the manufacturer's detailed instructions to ensure proper fitment and performance.
