Manley Chevrolet LS Piston Set - 4.130in Bore 1.315in CH, -31.00 CC

This set includes eight forged pistons from Manley Performance, designed for Chevrolet LS engines. These pistons feature a 4.130-inch bore, a 1.315-inch compression height, and a -31.00 CC dish volume. They are constructed from domestic 2618 alloy forgings, a material known for its exceptional strength and ability to handle high performance demands. The pistons also come standard with chrome moly wrist pins, and feature proven cam and barrel skirt profiles that help generate power while being easy on your cylinder walls.

Manley puts a lot of care into the details that make a difference in engine building. They use unique fixturing that allows them to machine the skirt and ring grooves in one operation, ensuring the ring grooves are perfectly square to the skirt. This attention to detail results in exacting ring lands and grooves, which is crucial for achieving a better ring seal and ultimately, more power. Professional engine builders and tuners often turn to Manley pistons because they trust the durability and performance these components offer for demanding builds.

When rebuilding or modifying your LS engine, these pistons are a solid option for those looking for robust internal components. Please note 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.
