The SuperPro fixed offset upper control arm kit (TRC6650) for 2009–2018 Chevrolet Silverado 1500 and GMC Sierra 1500 replaces stamped steel and aluminum alloy OEM upper arms and offers direct bolt‑on geometry correction for 2"–3" lifts. The design builds in camber and caster change for improved drivability straight out of the box. Paired with a heavy‑duty high‑articulation ball joint and SuperPro bushings, the kit can provide roughly 2.5–3.5° of caster increase and up to 1.5° of additional negative camber based on a 2" lift.
