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
