Rear Sway Bar

The Ultra Racing UR-AR19-391 is a 19mm rear sway bar engineered to combat chassis flex and enhance vehicle dynamics. During aggressive driving maneuvers such as fast cornering, hard braking, or rapid acceleration, the vehicle's chassis experiences significant weight transfer. This can cause one side of the car to bear substantially more force than the other, leading to chassis flex, vehicle body deformity, and a loss of tire grip. This manifests as negative handling traits like understeering or oversteering. The hollow steel tubes and oval tubes used for the bar itself range from 1.2mm to 1.6mm in thickness. This robust construction ensures rigidity and strength, maintaining consistent geometry under stress. Notably, the design also incorporates a crumple zone for enhanced safety during impacts. All raw materials undergo rigorous testing to guarantee optimal performance and durability. This means they bolt directly to existing chassis points. Installation is typically straightforward and can often be completed with basic hand tools within 30-60 minutes. The brand's involvement in motorsports, including track racing, autocross, and drifting competitions, further validates the performance and reliability of their chassis bracing solutions. This specific rear sway bar is designed for the Proton Preve 1.6T (2012 onwards) and Proton Suprima 1.6T (2013-2019) 2WD models.
