The idea of unifying quarks and leptons in a gauge symmetry is very appealing. However, such a unification gives rise to leptoquark-type gauge bosons for which current collider experiments put strong limits on their masses, well beyond the TeV scale. We present a model in the framework of extra dimensions which breaks such quark-lepton unification symmetry via compactification at the TeV scale. These color triplet leptoquark gauge bosons, as well as the new quarks present in the model, can be produced at the LHC with distinctive final-state signatures. These final-state signals include high pT multijets and multileptons with missing energy, monojets with missing energy, as well as the heavy charged particles passing through the detectors, which we also discuss briefly. The model also has a neutral standard model singlet heavy lepton which is stable, and can be a possible candidate for dark matter.
