About this part

Product Details

Manley Performance is well-known for building robust engine components that professional builders trust. This set of pistons is a prime example, designed for Chevrolet Small Block engines and featuring a 4.155-inch bore size. If you're assembling or rebuilding a high-performance small block Chevy, these pistons are engineered to handle the demands of serious power.

These pistons are forged from domestic 2618 alloy, a material chosen for its exceptional strength and ability to withstand high temperatures and pressures. They incorporate proven cam and barrel skirt profiles, which help generate significant 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. Manley's unique fixturing process allows them to machine the skirt and ring grooves in a single operation, ensuring perfect squareness between the two, which further contributes to that optimal ring seal.

Included with this set are premium chrome moly wrist pins, known for their durability. For those looking for even more resilience, Manley offers upgrades to 9310 or Turbo Tuff/DLC alloys on select part numbers. This piston set has a 4.00 CC dish volume, which is a key specification for determining compression ratio when paired with your cylinder heads and gasket thickness. Please note that these pistons are not CARB approved and cannot be shipped to California.
