Smooth out the ride and keep your rear tires planted with the Monroe OESpectrum Rear Suspension Shock Absorber 5545. It drops in as a direct-fit replacement for the 2016-2024 Honda Civic and 2019-2022 Honda Insight — see the Buyer's Guide tab for engine-level applications. Designed to restore a vehicle's original factory drivability, it delivers handling precision and control while filtering out noise, vibration and harshness.
- Reduced NVH: Twin Technology Active Control System delivers control under most driving conditions while isolating impact-related noise, vibration and harshness.
- Exceptional handling: Full displaced valving is tuned to each vehicle and adjusts to road extremes, while the larger bore provides more efficient damping control for a smooth, consistent ride.
- Control and durability: A PTFE-banded piston provides consistent sealing between the piston and pressure tube for better control and increased durability.
- Improved performance: Nitrogen gas-charge helps maintain tire-to-road contact by reducing aeration and shock fade.
OE all-weather fluid contains special additives to assist with extreme temperatures and help reduce oil breakdown, and a self-lubricating fluid seal retains gas while reducing friction against the piston rod. Backed by Monroe's Limited Lifetime Warranty and Feel the Difference Guarantee.
