This Icon Vehicle Dynamics 78601DJ tubular steel control arm kit for the GMC Sierra 1500 is a great suspension upgrade. The control arms are constructed from CNC bent 1026 DOM steel tubing and then powder coated semi-gloss black for maximum strength and corrosion resistance. These control arms are engineered with built in caster correction for optimal alignment specifications and smooth handling.
Delta Joint Difference - This control arm kit uses the unique and patented Delta Joint, a heavy duty high angle ball joint that combines the durability of a ball joint with the performance of a traditional uniball. Allowing for greatly increased articulation with little bind while also protecting from the elements. The Delta Joint features a zinc plated housing, providing the first layer of corrosion resistance, while a tough grease seal keeps potentially harmful elements out of the inner workings of the joint. A metal on metal construction and a greasable design increase the longevity of the Delta Joint while at the same time allowing for noise free operation.
