Smooth out the ride and keep your rear tires planted with the Monroe OESpectrum Rear Suspension Shock Absorber 5551. It installs as a direct-fit rear replacement for the 2015-2019 Hyundai Sonata, the 2017-2020 Kia Cadenza, and the 2016-2020 Kia Optima; see the Buyer's Guide tab for engine-level fitment. Designed to help restore the vehicle's original factory drivability and control, this OESpectrum shock filters out noise, vibration and harshness for a composed ride.

  • Reduced NVH: A Twin Technology Active Control System delivers control across most driving conditions while isolating impact-related noise, vibration and harshness.
  • Handling and damping: Full displaced valving is tuned to the vehicle and a larger bore provides more efficient damping for a consistent, smooth ride.
  • Control and durability: A PTFE-banded piston maintains consistent sealing between piston and pressure tube, while OE all-weather fluid resists breakdown at temperature extremes.
  • Tire contact: A nitrogen gas charge reduces aeration and shock fade to help maintain tire-to-road contact, and a self-lubricating fluid seal retains gas and reduces friction on the piston rod.

Backed by Monroe's Limited Lifetime Warranty and Feel the Difference Guarantee.

Frequently Asked Questions

What vehicles does the Monroe 5551 fit?

It's a rear shock absorber for the 2015-2019 Hyundai Sonata, 2017-2020 Kia Cadenza, and 2016-2020 Kia Optima. Check the Buyer's Guide tab to confirm engine-level fitment for your vehicle.

Is this a front or rear shock?

This is a rear suspension shock absorber. It is intended for the rear position on the listed applications.

How many should I order?

Shocks are best replaced as a pair. Order two so both sides on the axle are matched for balanced, even ride control.

What are signs my rear shocks may need replacing?

Common signs include excessive bouncing over bumps, a floating or unsettled ride, nose-diving on braking, and visible fluid leakage. Have the suspension inspected to confirm the cause.

What does the nitrogen gas charge do?

The nitrogen gas charge helps reduce aeration and shock fade, which helps maintain tire-to-road contact for improved ride and handling.
