Manley Chevrolet LS Piston Set - 4.165in Bore 1.315in CH, -11.00 CC

Manley Performance is well-known for building strong, reliable engine components for serious tuners and professional engine builders. This set of pistons is designed for Chevrolet LS engines and uses their signature "Platinum Series" construction. They feature 2618 alloy forgings, which are domestic-made to ensure they can handle the demands of a high-performance build. You'll also find proven cam and barrel skirt profiles that help generate power while being gentle on your cylinder walls, and exacting standards for ring lands and grooves to improve ring seal and overall power output.

These pistons come standard with 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 groove and the skirt, contributing to better performance and longevity. The -11.00cc dish volume is a specific design feature for certain LS engine builds, often used to achieve a desired compression ratio when paired with specific cylinder heads and crankshafts.

This piston set is a solid option for anyone rebuilding or upgrading their LS engine. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
