ICON Vehicle Dynamics Tubular Uniball Upper Control Arm System is a must have to add strenth and performance to your truck while on or off-road. Weak OEM ball joints present problems by limiting suspension travel potential, especially when using our 2.5” VS Series performance coil-over shocks on your truck. Our ICON tubular uniball upper control arms use 1” PTFE Lined Uniballs combined with a unique 17-4 Stainless Adapter system that increases the upper arms misalignment, allowing for smooth and clean wheel travel without worrying about factory ball joint bind. The ICON designed unique mounting adapter is an industry first making installation times much faster than other manufactureres arms.; These ICON engineered arms are built not only for added strength, but also to correct alignment geometry on lifted applications. Pair these Upper Control arms with a set of the ICON 2.5" Extended Travel Coil Over Shocks to get the maximum performance and suspension travel available to you.
