About this part

Product Details

When you're building a high-performance Small Block Chevrolet LS engine, getting the right pistons is crucial. This set from Manley Performance includes eight forged pistons, each designed for a 4.005-inch bore and featuring a 4-inch stroke with a 4cc flat top dish. These pistons are built using Manley's signature 2618 alloy forgings, which are known for their strength and ability to handle the demands of serious engine builds. They are designed to fit a wide range of popular LS-powered vehicles, including models like the Chevrolet Camaro, Corvette, and Pontiac GTO.

Manley puts a lot of thought into the details that make a difference. These pistons feature proven cam and barrel skirt profiles, which help them generate substantial power while also being gentle on your cylinder walls, contributing to longer engine life. The ring lands and grooves are machined to exacting standards, ensuring a better seal with your piston rings for improved power output. Each set comes standard with premium chrome moly wrist pins, and Manley's unique fixturing process allows for skirt turning and ring groove machining in a single operation. This ensures ultimate squareness between the piston skirt and the ring grooves, a critical detail for proper ring seal and performance.

This set is a solid choice for anyone looking to rebuild or upgrade their LS engine. They are designed for durability and performance, making them a popular option among professional engine builders. 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.
