Overview

The Ultra Racing UR-AR21-520 is a rear sway bar designed to improve vehicle handling by reducing chassis flex. During cornering, weight transfer can cause significant chassis distortion, leading to loss of tire grip and negative handling traits like understeer and oversteer. This sway bar helps to neutralize these forces, providing greater stability.
Show original supplier description
The Ultra Racing rear sway bar, model UR-AR21-520, is engineered to combat chassis flex that occurs during dynamic driving conditions such as hard cornering, braking, or acceleration. This flex can lead to reduced tire grip and undesirable handling characteristics like understeer or oversteer. The hollow steel and oval tubes used range from 1.2mm to 1.6mm in thickness, ensuring rigidity and strength. Specifically designed for the Mazda CX-5 KE models with 2.0L and 2.5L 2WD engines from 2012 to 2017, this 21mm solid rear sway bar is a direct fit. Installation is a straightforward bolt-on process. Some sources suggest that an alignment check may be advisable after installation. This rigorous testing ensures their components deliver competition-level performance suitable for everyday driving, while also adding an aesthetic appeal to the chassis.
