Detroit Diesel Specialists
Detroit powers most Freightliners and Western Stars, so the DD13, DD15, and DD16 are everyday work for us. With Detroit DiagnosticLink we diagnose the one-box aftertreatment, EGR, and turbo issues these engines are known for and handle the DT12 transmission and Detroit axles that go with them.
From a regen derate to a full in-frame, Detroit repair without the dealer wait.
