Overview

The Ultra Racing UR-AR18-290 is a rear anti-roll bar designed to improve vehicle handling.
Show original supplier description
The Ultra Racing rear sway bar is a 20mm diameter upgrade engineered to minimize chassis flex in the Hyundai Sonata and Kia Optima. By reducing body roll and rear chassis twist during cornering, this sway bar enhances stability and improves the rear-end grip, leading to a more predictable and precise handling experience. Its hollow steel construction is specifically tuned for the shared platform of these vehicles. Installation is straightforward thanks to direct OEM-point mounting, meaning no drilling or modifications are required. This rear sway bar is compatible with the Hyundai Sonata and Kia Optima from the 2011 model year through the present.
Vehicle Symptoms
