Smooth out a worn rear ride and bring back factory-tuned control with the Monroe OESpectrum Suspension Shock Absorber 5615, a rear-position damper designed to restore original drivability while filtering out noise, vibration and harshness. It installs as a direct-fit replacement for the 2006-2010 Kia Magentis, 2006-2010 Kia Optima, and 2007-2011 Kia Rondo — see the Buyer's Guide tab for engine-level details.
- Reduced NVH: Twin Technology Active Control System delivers control under most driving conditions while isolating impact-related noise, vibration and harshness.
- Tuned damping: Full displaced valving is tuned to the vehicle and adjusts to road extremes, while the larger bore provides more efficient damping control for a consistent, smooth ride.
- PTFE-banded piston: Provides consistent sealing between the piston and pressure tube for better control and increased durability.
- Nitrogen gas-charge: Helps maintain tire-to-road contact by reducing aeration and shock fade, and OE all-weather fluid resists breakdown in extreme temperatures.
Backed by Monroe's Limited Lifetime Warranty and Feel the Difference Guarantee. Shocks work as a matched pair — replacing both rear units together is recommended for balanced ride and handling.
