Manley Chevy LS Series 1.115in Bore 4.125in Stroke -18cc E/D

If you're building a high-performance Chevy LS engine, selecting the right pistons is a critical step. These Manley Performance "Platinum Series" pistons are forged from 2618 alloy, a material known for its strength and ability to handle the demands of powerful engines. They are designed with proven cam and barrel skirt profiles, which help generate power efficiently while also being considerate of your cylinder walls during operation. This attention to detail in the design means you get a well-built component that contributes to both performance and longevity.

Manley's commitment to precision is evident in their manufacturing process. They use unique fixturing that allows them to machine the piston skirt and ring grooves in the same operation. This ensures the ring grooves are perfectly square to the skirt, which is essential for achieving a solid ring seal. A good ring seal means better compression, more power, and less oil getting into the combustion chamber. These pistons also come standard with premium chrome moly wrist pins, and for some part numbers, upgrades to even more durable alloys are available. The exacting standards applied to the ring lands and grooves further enhance the ring seal, contributing to overall engine performance.

When you're putting together a serious engine build, components like these Manley pistons are what make the difference. They are a popular choice among professional engine builders and tuners who depend on reliable, high-performing parts. Remember 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.
