An ideal upgrade for added strength, these Xtreme Duty 4130 chromoly fabricated upper control arms with corrected pivot cups are self-lubricating with 1-ton HD spring-loaded ball joints and engineered to be free-floating, eliminating any friction that causes premature bushing failure. These UCAs can take a beating over any terrain, handle any extra weight from larger wheels and tires, making them some of the best control arms on the market! Frame side pivots include self-lubricating TCT bushings, plus forged torsion keys with shock spacers make adjustability a breeze and are engineered to last the lifetime of your truck.
