We perform a complete analysis of $\Delta S=2$ processes in the kaon system and evaluate $\Delta M_K$ and $\epsilon_K$ in the left-right supersymmetric model. We include analytic expressions for the contributions of gluinos, neutralinos and charginos. We obtain general constraints on off-diagonal mass terms between the first two generations of both down-type and up-type squarks. In the down-squark sector, we compare the results with gluino-only estimates. In the up-squark sector, we find a complete set of bounds on all combinations of chirality conserving or chirality flipping parameters. Finally, we comment on the size of the bounds obtained by imposing left-right symmetry in the squark sector.
