About this part

Product Details

Manley Performance is well-known for making strong engine components that professional builders trust. This set of pistons is designed for Chevrolet LS engines and is built using their signature "Platinum Series" construction. They start with domestic 2618 alloy forgings, which are chosen for their superior strength and ability to handle high performance demands. These pistons feature proven cam and barrel skirt profiles, designed to help generate power while also being gentle on your cylinder walls during operation.

You'll find exacting standards applied to the ring lands and grooves, which is crucial for getting a good seal with your piston rings. This enhanced ring seal directly translates to more power from your engine. The set includes premium chrome moly wrist pins, and Manley's unique fixturing process 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 overall engine reliability and performance.

This piston set has a 4.165-inch bore and a -20.00cc dish volume, making it suitable for specific engine builds where precise compression ratios are key. If you're rebuilding your LS engine for serious performance, these pistons offer a well-built foundation. Please note that these pistons are not CARB approved and cannot be shipped to California.
