Dualoy Cast Pistons

Dualoy cast pistons are designed for diesel and medium-duty gas engines. They're cast from aluminum and machined in-house to maintain the highest level of quality and consistency. The diesel applications feature an iron ring insert in the top ring groove designed to accept the Keystone-style top ring. Dualoy piston sets are available for most popular diesel light or medium-duty truck applications and engine codes.
