Looseness or Steering Play in some vehicle steering systems can often be attributed to a component known as a bell crank or idler, which supports the steering linkage. Original equipment designs utilize common sleeve bushings, which often wear out prematurely and cannot be adjusted for side play. In contrast, the Cognito SuperSteer bell cranks/idlers utilize tapered roller bearings, which are far better at carrying load. They can also be adjusted to achieve precise movement. If you're ready to upgrade your kit with the one of the nicest steering components that are guaranteed to fit then Cognito has you covered.
