Detailed Description

Dorman 521-115 is designed for rear suspension repair where the original lateral arm has worn bushings, loosened mounting points, or developed handling noise. It is a direct replacement for select 1999-2006 Hyundai Sonata, 2001-2006 Kia Magentis, 2001-2005 Kia Optima, 2001 Hyundai XG300, and 2002-2005 Hyundai XG350 applications.

What It Helps Fix

  • Handling instability from a damaged lateral link
  • Failed inspection due to worn rear suspension components

Installation Notes and Tips

Verify the exact year, make, model, and rear position before ordering. This Dorman 521-115 lateral arm is not adjustable, so alignment should be checked after installation on Hyundai Sonata, Kia Optima, Kia Magentis, Hyundai XG300, or Hyundai XG350 applications. Compare the original part shape, bushing layout, and mounting points to confirm correct rear lower forward, rear left, or rear right placement.

Quality Assurance
