We show that in supersymmetric extensions of the Standard Model gluino box diagrams can yield a large {Delta}I = 3/2 contribution to s {r_arrow} d{bar q}q FCNC processes, which may induce a sizable CP-violating contribution to the I = 2 isospin amplitude in K {r_arrow} {pi}{pi} decays. This contribution only requires moderate mass splitting between the right-handed squarks {tilde u}{sub R} and {tilde d}{sub R}, and persists for squark masses of order 1 TeV. Taking into account current bounds on Im {delta}{sub sd}{sup LL} from K-{bar K} mixing, the resulting contribution to {epsilon}{prime}/{epsilon} could be an order of magnitude larger than the measured value
