Manley Chevrolet LS Piston Set - 4.125in Bore 1.065in CH, -31.00 CC

When you're building a high-performance Chevrolet LS engine, you need components that can handle the stress and deliver consistent power. This set of Manley Performance pistons is designed for just that. You get eight forged pistons, each featuring a 4.125-inch bore, a 1.065-inch compression height, and a -31.00 CC dish. These aren't just any pistons; they are crafted from domestic 2618 alloy forgings, a material known for its exceptional strength and ability to withstand the demands of serious engine builds. The dish volume is crucial for setting your compression ratio, and this -31.00 CC dish is commonly used in applications aiming for specific performance targets.

Manley has put a lot of thought into the design of these pistons to ensure they perform well and last. They feature proven cam and barrel skirt profiles, which help generate power efficiently while also being designed to be gentle on your cylinder walls, reducing wear over time. The ring lands and grooves are machined to exacting standards, which is critical for achieving a good seal with your piston rings, leading to better combustion and more power. For added durability, these pistons come 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 the ring grooves are perfectly square to the skirt, contributing to overall engine health and performance. Select part numbers also include moly skirt coatings for even more reduced friction and wear.

This piston set is a solid choice for professional engine builders and tuners looking for reliable performance. 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, as well as any recommended complementary components for your specific build.
