Product Details

The Monroe OESpectrum line is aimed at OE-style replacement needs where ride quality and control matter. Part number 5646 uses a stem mount upper connection and a clevis bracket lower mount, making it a direct-fit rear shock absorber for the listed Kia and Hyundai applications. This part cross-references KYB 349243 for the same application.

Compatible with rear suspension service on 2011-2018 Kia Optima, 2012-2017 Hyundai Azera, 2014-2016 Kia Cadenza, 2013-2015 Hyundai Sonata, and 2011-2012 Hyundai Sonata without Factory Pro Kit. Monroe 5646 is a practical choice when replacing worn rear shocks on these vehicles and when maintaining OE-style ride response is a priority.

What It Helps Address

  • Excessive rear-end bounce over bumps
  • Loose or unsettled handling at the rear of the vehicle
  • Noise and harshness from worn shock absorbers
  • Reduced ride control during everyday driving
  • Uneven damping response from aging suspension components

Installation Notes

Verify rear fitment by year, make, model, and the Sonata note for 2011-2012 vehicles without Factory Pro Kit before installation. Confirm the stem upper mount and clevis bracket lower mount match the original hardware layout on the vehicle. Inspect surrounding suspension components, including mounts and bushings, before replacing the shock absorber.

Quality Assurance

Monroe OESpectrum shock absorbers are engineered to return the vehicle closer to factory ride behavior while maintaining controlled damping and reduced harshness. Part number 5646 is built for the listed rear applications and follows Monroe’s OE-style replacement approach.
