We consider SU(3)C×SU(2)AL×SU(2)BL×U(1)Y as the low-energy subgroup of supersymmetric SU(3)6 unification. This may imply small deviations from quark-lepton universality at the TeV scale, as allowed by neutron-decay data. New particles are predicted with specific properties. We discuss, in particular, the new heavy gauge bosons corresponding to SU(2)AL×SU(2)BL→SU(2)L.
