About this part

Product Details

Built from domestic 2618 alloy forgings, these Manley pistons are a solid choice for serious LS engine builds. The 4.135-inch bore size and -18.00cc dish volume are common for many popular LS engine configurations, especially those looking for a specific compression ratio when paired with appropriate cylinder heads and head gasket thickness. The 1.115-inch compression height is also a key measurement that determines piston-to-valve clearance and overall deck height.

Manley doesn't cut corners here. You'll find proven cam and barrel skirt profiles designed to reduce friction and wear on your cylinder walls while still making substantial power. They also pay close attention to the details that matter for sealing, with exacting standards for ring lands and grooves. This attention to detail helps ensure a better ring seal, which translates directly to more power and improved engine efficiency. Each set comes standard with premium chrome moly wrist pins, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the skirt for optimal performance.

If you're rebuilding a Chevrolet LS engine and need a set of pistons that can handle the demands of performance tuning and durability, these Manley pistons are a well-known option among professional engine builders. Keep in mind that these are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
