Smooth out the rear ride and keep the tires planted with the Monroe OESpectrum Rear Suspension Shock Absorber 5646. This rear-position shock is a direct-fit replacement for the 2011-2015 Hyundai Sonata, 2012-2017 Hyundai Azera, 2014-2016 Kia Cadenza, and 2011-2018 Kia Optima — see the Buyer's Guide tab for engine details. Designed to help restore a vehicle's original factory drivability, the OESpectrum line delivers a good level of handling precision and control while damping out noise, vibration, and harshness.
- Reduced NVH: Twin Technology Active Control System is built to keep control under most driving conditions while isolating impact-related noise, vibration, and harshness.
- Exceptional handling: Full displaced valving, tuned to each vehicle, adjusts to road extremes, and the larger bore provides more efficient damping control for a consistent, smooth ride.
- Control and durability: A PTFE-banded piston provides consistent sealing between the piston and pressure tube for better control and increased durability.
- Consistent ride: OE all-weather fluid uses special additives to assist with extreme temperatures and help reduce oil breakdown, and a nitrogen gas charge helps maintain tire-to-road contact by reducing aeration and shock fade.
Backed by Monroe's Limited Lifetime Warranty and the Feel the Difference Guarantee. Shocks work as a pair — replace both rear units together for balanced ride control.
