United Engine & Machine has been manufacturing aftermarket pistons for automotive, light truck, popular import and heavy-duty applications since 1922. We offer over 485 OE replacement pistons.
Our Silv-O-Lite pistons are engineered to offer the best bang for your hard-earned bucks. Each Silv-O-Lite piston is manufactured from cast aluminum and then machined to produce a unique diamond finish, all to exacting skirt tolerances. It is then heat-treated and machined for strength and durability, tighter piston-to-cylinder wall clearances, and longer piston life.
Look at our catalog and find the right Silv-O-Lite piston for your application.View Products »
