A non-abelian kink inducing asymptotically the breaking pattern $SU(5)\timesZ_2\rightarrow SU(4)\times U(1)/Z_4$ is obtained. We consider a fourth orderHiggs potential in a $1+1$ theory where the scalar field is in the adjointrepresentation of $SU(5)$. The perturbative stability of the kink is alsoevaluated. A Schr\"odinger-like equation for the excitations along each $SU(5)$generator is determined, and in none of the cases negative eigenvaluescompromising the stability of solution are found. In particular, severalbounded scalar states are found, being one of them the translational zero modeof the flat space $SU(5)\times Z_2$ kink.
