20mm Rear Anti-Roll Bar

The Ultra Racing URKR-AR20-627 is a 20mm rear anti-roll bar engineered to combat chassis flex and improve vehicle dynamics. During aggressive driving, such as fast cornering, hard braking, or acceleration, the chassis experiences significant forces due to weight transfer. This can lead to as much as three times more force on one side of the vehicle than the other, causing chassis flex, deformation, and tire grip loss. Such issues can manifest as negative handling traits like understeer and oversteer. This anti-roll bar addresses these issues by significantly reducing body roll during cornering, thereby improving stability and steering response. The brackets are constructed from steel plates between 4mm and 5mm thick, while the hollow steel tubes and oval tubes are between 1.2mm and 1.6mm thick. This involvement allows them to gather crucial feedback for product enhancement. The brand is a chassis tuning partner for several racing teams, showcasing its capabilities in demanding motorsport environments. The URKR-AR20-627 is specifically designed for the Kia Stinger (CK) models with 2.0D/3.3 engines, available in 2WD/4WD configurations, from 2018 onwards.
