About this part

Product Details

Manley Performance offers this forged piston set specifically for Chevrolet LS engines. These pistons feature a 4.125-inch bore and a -18.00cc dish, with a 1.115-inch compression height. They are built using domestic 2618 alloy forgings, known for their exceptional strength and performance under demanding conditions. This makes them a solid choice for serious engine builds where reliability and power are key.

The design incorporates proven cam and barrel skirt profiles, which help generate substantial power while minimizing wear on cylinder walls. Manley's manufacturing process uses unique fixturing that allows for skirt turning and ring groove machining in a single operation. This ensures ultimate squareness between the ring grooves and the piston skirt, contributing to enhanced ring seal and ultimately, more power. The exacting standards applied to the ring lands and grooves further improve ring seal. This set includes tool steel wrist pins for added durability.

This piston set is a popular choice among professional engine builders and tuners who depend on Manley pistons for superior performance and durability in their builds. Please note that this part is not CARB approved and cannot be shipped to California.
