To suit 22mm diameter sway bars - the DIY (Do It Yourself) alloy lateral locking system can be utilized on both factory and more importantly aftermarket sway bars. The locks are easily installed on car with no need to remove the sway bar to install. They are mounted directly next to the sway bar mounting points and prevent shifting or sideways movement of the sway bar under lateral (cornering) loads. This results in improved sway bar effectiveness whilst preventing fouling of the sway bar on near by chassis and steering components.
