About this part

Product Details

Starting with domestic 2618 alloy forgings, these Manley Platinum Series pistons are built for serious performance in your Small Block Chevrolet LT1 or LT4 engine. They feature a -10cc dish, a 4.075 inch bore, and a 4 inch stroke, making them a solid choice for rebuilding or upgrading your engine's rotating assembly. Professional engine builders and tuners trust Manley for the strength and durability their pistons offer.

Manley's signature cam and barrel skirt profiles are designed to generate substantial power while also being gentle on your cylinder walls, which helps extend the life of your engine build. They also pay close attention to the ring lands and grooves, holding them to strict standards to ensure an enhanced ring seal, which translates directly to more power. The unique fixturing Manley uses allows them to machine the skirt and ring grooves in a single operation, ensuring ultimate squareness between the two critical areas.

Included with this set are premium chrome moly wrist pins, known for their strength. For those looking for even more durability, Manley offers upgrades to 9310 and Turbo Tuff/DLC alloys on select part numbers. These pistons are not CARB approved and cannot be shipped to California.
