We consider an explanation of the CDF II W boson mass anomaly bymixing withgauge symmetry under which right-handed fermions are charged. It is found thatis preferred to be leptophobic to accommodate the anomaly while avoiding other experimental constraints. In such a case we require extra charged leptons to cancel quantum anomalies and the SM charged leptons get masses via interactions with the extra ones. These interactions also induce muonand lepton flavor violations. We discuss muon, possible flavor constraints, neutrino mass generation via inverse seesaw mechanism, and collider physics regardingproduction for parameter space explaining theboson mass anomaly.
