About this part

Product Details

This set includes eight Manley Platinum Series pistons, designed for Chevy LT1 Direct Injected engines. Each piston features a -20cc dish and a 4.070-inch bore, with a 4.00-inch stroke compatibility. These pistons are built using domestic 2618 alloy forgings, a material known for its exceptional strength and performance under demanding conditions. They also come standard with premium chrome moly wrist pins, contributing to their overall durability.

Manley's Platinum Series pistons incorporate proven cam and barrel skirt profiles. These profiles are engineered to help generate significant power while also being designed to minimize wear on your cylinder walls. The ring lands and grooves are machined to exacting standards, which is crucial for achieving an enhanced ring seal. A tighter ring seal means better combustion efficiency and ultimately, more power from your engine. The unique fixturing Manley uses allows for skirt turning and ring groove machining in a single operation, ensuring the ring grooves remain perfectly square to the piston skirt for optimal performance.

These pistons are a solid choice for serious engine builders looking for reliable components for their high-performance builds. They are not CARB approved and cannot be shipped to California. Please refer to the manufacturer's installation instructions for details on proper fitment and assembly.
