Kelvin Diolisel Lopez Perez, 28, of Dorchester, and Christopher Antonio Guzman De Los Santos, 23, of Dedham, were taken into custody during a traffic stop in Concord at 11 a.m.
Both men face charges of controlled sales of fentanyl greater than 5 ounces and controlled sales of methamphetamine greater than 5 ounces.
Guzman De Los Santos faces an additional charge of felonious use of a firearm.
