Set of 8 Moresa .020 hypereutectic flat top pistons and a moly piston ring set for 2004-2008 GM 6.0L V-8 engines requiring a flat top piston with floating pins. 

This piston set has floating pins and cannot be used with the earlier model press-fit connecting rods, due to different pin diameters. Before ordering, confirm that you need dish top pistons with floating pins.
