⚠️ IMPORTANT FITMENT NOTE: Please verify your vehicle's production year before ordering. These rear shocks are engineered specifically for 1979 through 1984 models and will not fit 1985 and newer vehicles. The 1979–1984 model years utilize a smaller 16mm lower mounting pin configuration and a shorter overall travel length. 1985 and newer models upgraded to a larger 19mm pin standard and require longer shock lengths. If you are ordering for a 1985 or newer vehicle, please search our site for the 1985+ matching part numbers or contact us so we can guide you to the correct setup.
