Manley Chevrolet Small Block Piston Set - 4.035in Bore 1.125in CH, -4.00 CC

Forged from domestic 2618 alloy, these Manley pistons are built for serious performance in Chevrolet Small Block engines. The 4.035-inch bore size and -4.00cc dish volume are key specifications for builders looking to achieve specific compression ratios and displacement targets. This material choice is crucial for handling the increased cylinder pressures and temperatures found in performance applications, offering a strong foundation for your engine build.

Manley's signature cam and barrel skirt profiles are designed to reduce friction and wear on cylinder walls while still generating substantial power. They've also paid close attention to the details that matter for sealing: exacting standards for ring lands and grooves ensure a tight seal, which translates directly to more power and better engine efficiency. The included tool steel wrist pins are well-built for durability, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the skirt, a detail that professional engine builders rely on for optimal performance and longevity.

This set is intended for builders who understand the nuances of engine assembly and are looking for well-made components to match their expertise. Because these are performance-oriented pistons, it's important to consult with your engine builder or refer to Manley's detailed installation instructions to ensure proper fitment and assembly with your chosen crankshaft, connecting rods, and ring set. Please note that this part is not CARB approved and cannot be shipped to California.
