Manley Chevrolet Small Block Piston Set - 4.030in Bore 1.125in CH, -15.00 CC

Manley Performance is well-known for building robust engine components, and their Platinum Series pistons are a prime example of that commitment. If you're building a high-performance Chevrolet Small Block engine, this set of pistons is designed to handle the demands of serious power. They feature a 4.030-inch bore size and a -15.00 CC dish, which is a specific volume that affects your engine's compression ratio. These aren't just off-the-shelf parts; they're crafted with the kind of attention to detail that professional engine builders rely on.

What sets these pistons apart is the material and the machining. They're forged from domestic 2618 alloy, a material chosen for its exceptional strength and ability to withstand high temperatures and pressures without deforming. The cam and barrel skirt profiles are carefully engineered to reduce friction and wear on your cylinder walls while still allowing the piston to generate significant power. You'll also find exacting standards applied to the ring lands and grooves, which is crucial for ensuring a tight seal with your piston rings. This improved seal means better combustion efficiency and, ultimately, more power from your engine. The included wrist pins are made from premium chrome moly steel, offering solid durability for most performance builds.

When you're putting together a performance engine, every component matters. These Manley pistons are made using unique fixturing that allows them to machine the skirt and ring grooves in a single operation. This ensures the ring grooves are perfectly square to the piston skirt, which is vital for optimal ring seal and consistent performance. While these pistons are built for durability and performance, please note they are not CARB approved and cannot be shipped to California. If you're looking for a well-built foundation for your next Chevrolet Small Block build, this set of Manley pistons is a solid choice.
