Manley Small Block Chevy 4.030in Bore 1.550in CD -2.5cc Dish Platinum Series Pistons - E/D

Manley Performance is well-known for making strong engine components, and their Platinum Series pistons are a prime example of that commitment. If you're building a Small Block Chevrolet engine and need a reliable set of pistons, these are designed to handle serious work. They feature a -2.5cc dish volume and a 4.030-inch bore size, making them suitable for many performance builds.

These pistons are forged from domestic 2618 alloy, which is chosen for its superior strength and ability to perform under demanding conditions. Manley also uses proven cam and barrel skirt profiles that help generate power while being considerate of your cylinder walls. The ring lands and grooves are machined to exacting standards, which is crucial for getting a good seal from your piston rings and maximizing power output. A unique fixturing process ensures the ring grooves are perfectly square to the skirt, contributing to overall engine health and performance.

Included with these pistons are premium Chrome Moly wrist pins, known for their durability. For those looking for even more robustness, Manley offers upgrades to 9310 and Turbo Tuff/DLC alloys on select part numbers, though this specific set comes standard with Chrome Moly. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They are designed for performance applications and are a solid choice for engine builders aiming for durability and power.
