We have just developed a kit for the SsangYong Rexton and Mercedes ML rear end. This kit allows for towing and heavy loading without running on the bumpstops. As always the kit can be fitted using schrader valves or with a more sophisticated controller to allow control from the dashboard (or boot). The kit is easily fitted by a mechanic and includes everything needed to convert the rear end, including upper and lower brackets, bags, valves and line. No drilling or cutting is required and the conversion is fully reversible if you trade or sell your vehicle.
