We investigate black brane solutions in asymptotically Lifshitz spacetime in 
-dimensional Horndeski gravity, which admit a critical exponent fixed at 
. The cosmological constant depends on z as 
. We compute the shear viscosity in the 
-dimensional dual boundary field theory via holographic correspondence. We investigate the violation of the bound for a viscosity to entropy density ratio of 
at .
