We establish some signatures of the extra bilepton boson ${X^0}$ predicted in the ${SU (3)_C times SU (3)_L times U (1)_X}$ model with right-handed neutrinos. We analyze the process $p + p longrightarrow X^0 +X^{0*} + {hbox {anything}}$, for center of mass energy regime of the Large Hadron Collider. The main contributions for the neutral bilepton production in $q bar q$ process come from the $s-$channel ($Z$ and $Z^prime$ exchanges), when the initial quarks have charge 2/3, and from an additional $t-$channel (heavy quark exchange) when they have -1/3 of the positron electric charge. We calculate some distributions of the final bileptons and from these results we conclude that LHC can show a clear signature for the existence of the $X^0$ predicted in the 3-3-1 model.
