Manley Chevrolet LS Piston Set - 4.080in Bore 1.065in CH, -31.00 CC

Built from domestic 2618 alloy forgings, these Manley pistons are designed for serious performance builds in Chevrolet LS engines. The 4.080-inch bore size and -31.00 CC dish volume are key specifications for achieving specific compression ratios in your engine build. Manley's commitment to precision is evident in their exacting standards for ring lands and grooves, which directly contribute to better ring seal and ultimately, more power from your engine.

You'll find that these pistons feature proven cam and barrel skirt profiles. This design choice helps manage piston movement within the cylinder, reducing wear on the cylinder walls while still allowing the piston to generate substantial power. Manley's unique fixturing process allows them to machine the skirt and ring grooves in a single operation. This ensures the ring grooves remain perfectly square to the piston skirt, a critical detail for optimal engine performance and longevity. Each set includes premium chrome moly wrist pins, known for their durability, and many part numbers also come with a moly skirt coating for added protection.

When you're building a high-performance LS engine, the details matter. These Manley pistons are a solid choice for professional engine builders and tuners looking for reliable components that can handle demanding applications. 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.
