Designed to bring back the factory ride and handling feel, the Monroe OESpectrum 5551 rear shock absorber is a direct-fit replacement for the listed 2015-2019 Hyundai Sonata, 2016-2020 Kia Optima and 2017-2020 Kia Cadenza applications. This Monroe suspension shock absorber is built for precise handling and control, and it filters out noise, vibration and harshness to enhance drivability. See the "Vehicles it fits" section for trim and engine details.
- Reduced noise, vibration and harshness: Monroe's Twin Technology Active Control System is designed to deliver control in most driving conditions while isolating impact-related noise, vibration and harshness.
- Exceptional handling: Full displaced valving, tuned to each vehicle, adjusts to road extremes. The larger bore gives more efficient damping control for a consistent, smooth ride.
- Control and durability: A PTFE-banded piston seals consistently against the pressure tube for better control and increased durability. A self-lubricating fluid seal holds in the gas and cuts excess friction on the piston rod to help reduce premature wear.
- Consistent ride: OE all-weather fluid carries special additives that help it handle extreme temperatures and help reduce oil breakdown. A nitrogen gas charge helps keep the tires in contact with the road by reducing aeration and shock fade.
Each shock comes with Monroe's Limited Lifetime Warranty and its exclusive Feel the Difference Guarantee.

Frequently Asked Questions
Is this 2015-2019 Hyundai Sonata shock absorber for the front or the rear?
It is a rear shock absorber for the 2015-2019 Hyundai Sonata. The "Vehicles it fits" section lists trim and engine details.
Can I use it as a 2016-2020 Kia Optima shock absorber?
Yes. It is also listed as a rear shock for the 2016-2020 Kia Optima and the 2017-2020 Kia Cadenza.
What does the nitrogen gas charge do?
The nitrogen gas charge reduces aeration and shock fade. This helps keep the tires in contact with the road, which supports ride and handling.
What are signs a rear shock absorber may need replacing?
Common signs include excessive bouncing after bumps, fluid leaking from the shock body, rear-end sway or squat, and uneven tire wear. Diagnose the cause before replacing parts.
Should I replace both rear shocks at the same time?
Replacing both rear shocks together is recommended for balanced ride and handling. A new shock paired with a worn one can make the rear feel uneven.
