Installation Notes and Tips

Install on the front left lower position only. Verify vehicle year, make, model, and trim before ordering, especially on Hyundai Ioniq, Kia Niro, Kia Niro EV, Hyundai Kona Electric, and Kia Soul EV applications. Because the assembly is non-adjustable, confirm suspension alignment after installation. Replace the cotter pin during service and torque all fasteners to factory specifications.
