Keith Black Dualoy Diesel Pistons: A Better Replacement Piston for Your Oil Burner

Diesel engines never die, they just get rebuilt. Keith Black knows that and now Dualoy OEM replacement pistons for Chevy, Ford, and Dodge diesel engines.

Back in the 1950s United Engine, now the parent company for Keith Black and Silv-o-Lite pistons, developed the method for casting pistons for diesel engines with an iron insert for the top ring. Keith Black brought the design back for the new Dualoy pistons.

Why the iron insert? Truck engines, especially diesels, exert enormous pressure on the top rings. Without the insert, the ring would beat itself against the piston’s softer aluminum alloy, eventually destroying both. The Dualoy’s iron insert provides a very hard surface for the top ring to ride against without damaging itself or the piston.

Keith Black Dualoy pistons are available for popular light-duty diesels in standard bore and oversizes depending on the application. They are available in weight-matched sets of eight or individually.
