Does your 87-95 Jeep YJ or 97-02 Wrangler TJ have a little drive line vibration after installing a lift? This 3/4" transfer case drop kit might just be the answer. Typically used with 2.5-3" lifts when the stock slip yoke rear driveshaft is retained. This system comes with new fasters and lowers the transfer case to reduce the rear driveline angles.
