The X-Eng X-Deflex kit is a Disconnectable Anti-Sway (Anti-Roll) bar system. The kit suits Defender and enables the user to easily disconnect the anti-sway bar instantly for off-road operations to achieve maximum articulation, while allowing it to be re-connected when needed for high speed roads. The system is compatible with extreme travel suspensions up to 16". Some models will require simple spacers to be fitted dependent on fuel tank locations.
