Product Details
Manley Performance is well-known for making strong engine components, and their Platinum Series pistons are a prime example of that expertise. If you're building or rebuilding a Chevrolet Small Block engine and need a set of pistons that can handle serious work, these are a solid option. They feature a 4.040-inch bore size, a 1.250-inch compression height, and a -2.50cc valve relief, which are key dimensions for getting your engine's compression ratio dialed in just right.
These pistons are forged from domestic 2618 alloy, a material chosen for its exceptional strength and ability to perform under high stress. Manley also uses proven cam and barrel skirt profiles, which help these pistons generate substantial power while also being designed to be gentle on your cylinder walls. The ring lands and grooves are machined to exacting standards, which is crucial for achieving a tight ring seal and maximizing the power your engine makes. They come standard with premium chrome moly wrist pins, and for some part numbers, upgrades to even more durable alloys are available. Manley's unique fixturing process allows them to machine the skirt and ring grooves in a single operation, ensuring perfect squareness between the two critical areas.
When you're putting together a high-performance engine, the details matter. These Manley pistons are built with those details in mind, aiming for both power and durability. Keep in mind that these are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
