Product details
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 SuperSteer bell cranks/idlers utilize tapered roller bearings, which are far better at carrying load. They can also be adjusted to achieve precise movement. Supersteer Idler Arm Support for 2011-2024 Silverado/Sierra 2500/3500 2WD/4WD supports the idler arm to reduce steering flex and improve steering response.
