Designed for 2005-2008 Gen III Hemi 5.7 litre engine builds, this hypereutectic cast alloy dome top piston set is a practical choice for a freshen-up, rebuild or performance-minded restoration where strength, consistency and correct fitment matter. The hypereutectic alloy construction offers improved thermal stability and wear resistance compared with conventional cast pistons, making it well suited to street-driven engines and spirited weekend use.

The dome top design is intended to help maintain compression, while the 1.205 inch compression height and 1.5mm, 1.5mm, 3.0mm ring groove package suit early Gen III Hemi style piston and ring specifications. With a 100mm finished bore size, these pistons are suited to blocks being machined oversize from the original 99.50mm bore. As with any engine build, final bore size, piston-to-bore clearance, ring selection and ring end gap should be confirmed by your engine machinist before assembly.

A solid replacement piston set for Chrysler and Dodge 5.7 Hemi owners wanting dependable components for a properly machined engine rebuild.
