Manley Chevrolet LS Piston Set - 4.135in Bore 1.115in CH, -29.00 CC

Built from domestic 2618 alloy forgings, these Manley pistons are designed to handle the demands of high-performance Chevrolet LS engines. The 4.135-inch bore size and -29.00cc dish volume are specific choices that contribute to optimized compression ratios and combustion chamber shapes for boosted or naturally aspirated builds.

Manley's signature cam and barrel skirt profiles are a key feature here, helping to reduce friction and wear on your cylinder walls while still generating substantial power. They've also paid close attention to the ring lands and grooves, holding them to exacting standards to ensure a better ring seal, which directly translates to more power and improved efficiency. The included chrome moly wrist pins are well-built and durable, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the piston skirts, a detail that matters for long-term reliability and performance.

This set is a solid choice for professional engine builders and tuners looking for robust components for their LS engine projects. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a complete build, you'll want to ensure you have the correct supporting components like rings and connecting rods, as these are sold separately.
