Description

The Silvolite S1489H.030 is a hypereutectic aluminum piston designed for stock engine stroke applications. It features a flat top piston style with no valve reliefs and a bore size of 4.030 inches (102.362mm).

These pistons utilize an aluminum alloy high in silicon, offering greater strength and resistance to scuffing and seizing. They also provide improved groove wear and resist cracking in the crown area. The pistons have reinforced top lands and diamond-finished skirts, making them suitable for a variety of automotive applications. This piston is sold individually and does not include piston rings.
