We compute the spin-2 Kaluza-Klein modes around a warped product of AdS₄ and a seven-ellipsoid. This background with global G₂ symmetry is related to a U(N) × U(N) N = 1 superconformal Chern-Simons matter theory with sixth order superpotential. The mass-squared in AdS₄ is quadratic in G₂ quantum number and KK excitation number. We determine the dimensions of spin-2 operators using the AdS/CFT correspondence. The connection to N = 2 theory preserving SU(3) × U(1)_R is also discussed.
