Manley Chevrolet Small Block Piston Set - 4.045in Bore 1.550in CH, -4.00 CC

Manley Performance is well-known for building robust engine components, and their Chevrolet Small Block Piston Set is a prime example of that commitment. If you're building or rebuilding a performance engine for your classic or modern Chevrolet, these pistons are designed to handle the demands of serious tuners and engine builders. They feature a 4.045-inch bore and a 1.550-inch compression height, with a -4.00cc valve relief, making them a solid choice for many small block Chevy applications.

What sets these pistons apart is the material and the manufacturing process. They are forged from domestic 2618 alloy, which offers superior strength and performance compared to cast aluminum, making them ideal for high-stress environments. The cam and barrel skirt profiles are proven to generate substantial power while also being designed to be gentle on your cylinder walls, which helps with longevity. Manley also pays close attention to the details, with exacting standards for ring lands and grooves to ensure enhanced ring seal and ultimately, more power. Their unique fixturing process allows for skirt turning and ring groove machining in a single operation, ensuring ultimate ring groove to skirt squareness for optimal performance.

This set includes premium chrome moly wrist pins, known for their durability. For those looking for even more resilience, Manley offers upgrades to 9310 and Turbo Tuff/DLC alloys on select part numbers. It's important to note that these pistons are not CARB approved and cannot be shipped to California. When planning your build, ensure you have the correct supporting components like rings and connecting rods to match these high-performance pistons.
