One area seriously lacking on the Chevy Silverado and GMC Sierra is the steering link. With an outside diameter of only 1/2", one wrong turn can easily bend the tie rod leaving your alignment out of whack. The problem is intensified when you add off-road tires and wheels. The tie rod sleeve upgrade by Rough Country takes the outside diameter from 1/2" to 1” strengthening the steering components with an install time of one hour. Takes the place of the stock jam nut.
