In this article, we investigate stochastic comparisons of the lifetimes of series and parallel systems comprising components following the scale-additive hazard rate model, subject to random shocks, where dependence among component lifetimes is modeled via Archimedean copulas. By imposing suitable conditions on the baseline distribution, model parameters, generator functions, and shock occurrence probabilities, we establish sufficient criteria for comparing the lifetimes of two systems under both the usual stochastic order and the hazard rate order. The results demonstrate how parameter heterogeneity and dependence structure simultaneously influence system reliability. Several numerical examples are also provided to substantiate the theoretical findings.
