Optimize and improve the steering geometry and strength of your vehicle with a pair of Skyjacker Upper Control Arms. With the revised steering geometry you get increased suspension travel, and our Upper control arms are manufactured in-house in the USA. They are made of high-strength DOM tubing to withstand extreme amounts of stress and loads, and a gusset plate stiffener is welded in between the A-arms for added rigidity and strength. You are not only increasing on-road handling but also off-road strength and capability when you choose a set of Skyjacker Upper Control Arms. Our UCA's include an optimum pivot ball joint for improved flexibility and to reduce stress. Ball joints are greasable to increase service life. 100% bolt-on.
