SuperSteer SS175 Idler Arm Support for GM Trucks, Vans and SUVs 1999-2010 (Does not include idler arms). Have you begun to notice loose or sloppy steering in your GM truck, van or SUV? It could be because the original idler arm support has worn out, especially if you run larger than stock tires. The factory idler arm support uses common sleeve bushings, which eventually wear out, creating excessive play in the steering system. The SuperSteer SS170 idler arm support features a stronger cast aluminum housing and heavy-duty tapered roller bearings to reduce play and restore steering precision. A direct replacement for the factory part, the SuperSteer SS175 is made in the USA and comes with all necessary mounting hardware. Contact seller for correct application.
