Description

The United Engine & Machine Co Silv-O-Lite 3498HC.25MM is a set of hypereutectic pistons designed for enhanced strength and scuff resistance. These pistons feature a flat top design with no valve reliefs, a 3.908-inch bore, and a 1.330-inch compression height. They utilize an aluminum alloy high in silicon for improved durability.

These pistons are designed for a press-fit wrist pin style and have a 1.5mm x 1.5mm x 3.0mm ring groove thickness. They are sold as a set of 8 and include the wrist pins, but not the retainers or piston rings. The pistons feature a coated skirt and require shallow rings.
