Heavy-duty control arms and ball joints are essential for giving your truck an excellent ride quality. Our selection of Control arms is the best choice for those looking for improved ride quality and control, especially those who lifted their truck. The factory control arms aren't designed for lifted suspensions; thus, won't provide with great ride quality. Our selection of Control Arms is built to correct front end alignment after lifting your truck to provide great steering responsiveness! Ball Joints are a weak point for the GM 2500HD/3500HD, they typically wear our quickly, especially for those running larger wheels and tires. Our selection of heavy-duty ball joints is the perfect upgrade to your worn-out factory ball joints.
