PLATINUM SERIES LIGHTWEIGHT PISTONS - learn more about pistons
Manley pistons are machined of high strength 2618 material. Each design is lightweight yet robust enough to deliver long service life. Perfect ring groove to skirt squareness is achieved through our unique "one fixturing" manufacturing method that assures maximum horsepower. Roundwire locks and pressure balance grooves are included with every set at no additional charge. Compression ratios for the 5.7L are calculated at .003 deck clearance and a 3.941 head gasket ID with a .028 compressed thickness. Compression ratios for the 6.1L are calculated at .003 deck clearance and a 4.100 head gasket ID with a .040 compressed thickness. Compression ratios for the 6.4L are calculated at .012 deck clearance and a 4.090 head gasket ID with a .027 compressed thickness.

Premium Chrome Moly wrist pins are included with the Standard Series and 9310 Alloy wrist pins are included with the Extreme Duty Series.
