Manley Chevrolet Small Block Piston Set - 4.040in Bore 1.125in CH, 11.00 CC

If you're building a high-performance Chevrolet small block engine, this Manley Performance piston set is a solid choice. These pistons are designed for a 4.040-inch bore and feature a 1.125-inch compression height, with a dish volume of 11.00 CC. They are forged from 2618 alloy, a material known for its exceptional strength and durability, making them well-suited for demanding engine builds. Professional engine builders and tuners often turn to Manley pistons because they trust the brand for reliable performance.

Manley uses domestic 2618 alloy forgings, which offer superior strength compared to cast aluminum, ensuring these pistons can handle the stresses of a performance engine. They come standard with premium chrome moly wrist pins, and for some part numbers, upgrades to even stronger alloys like 9310 or Turbo Tuff/DLC are available, offering additional durability. The ring lands and grooves are machined to strict standards, which helps achieve a better ring seal, ultimately leading to more power. The pistons also feature cam and barrel skirt profiles that are designed to generate significant power while minimizing wear on the cylinder walls. Manley's unique fixturing process allows them to machine the skirt and ring grooves in a single operation, ensuring perfect squareness between the ring grooves and the skirt for optimal performance.

This set includes pistons, chrome moly wrist pins, and ring sets. It's important to 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 when rebuilding your engine.
