Description

The Silvolite 3459HC.1.0MM is a set of 6 hypereutectic aluminum pistons designed for GM V6 engines. These pistons feature a dish style with no valve reliefs and a 90.000mm bore size. They utilize a press-fit wrist pin style and are sold as a set of 6.

The pistons are constructed from a high-silicon aluminum alloy for increased strength, scuff, and seizure resistance, with improved groove wear and crown area crack resistance. They have a coated skirt and require shallow rings.
