Description

The Silv-O-Lite 3459HC.1.5MM is a set of hypereutectic pistons designed for GM V6 engines with a 90.5mm bore. These pistons are constructed from a high-silicon aluminum alloy for increased strength, scuff resistance, and improved groove wear.

Featuring a dish-style piston head with no valve reliefs, these pistons have a compression height of 1.478 inches and a piston head volume of +26.00cc. They utilize shallow ring grooves and require 1.20mm x 1.50mm x 3.00mm piston rings. The included wrist pins are press-fit style, and the pistons come with coated skirts. This set is sold as a quantity of 6.
