99-06 GM 1500 4wd Upper Control Arm
There are multiple issues when lifting your vehicle with stock upper control arms. Both the geometry and strength are compromised due to over articulating the stock arms. We solved these problems by designing our upper control arms with increased castor and repositioned pivot angles reducing stress on the joints. The increased castor allows for proper alignment and improved handling.
