Smooth out the ride and keep the rear wheels planted with the Monroe OESpectrum Suspension Shock Absorber 5540. This nitrogen gas-charged shock installs as a direct-fit rear replacement for the 2014-2018 Mazda 3 — see the Buyer's Guide tab for the engine-level fitment. Monroe OESpectrum passenger-car shocks are designed to help restore a vehicle's original factory drivability 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 specifically to the vehicle, 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.
- Gas-charged design: Nitrogen gas-charge helps maintain tire-to-road contact by reducing aeration and shock fade, while the self-lubricating fluid seal retains gas and reduces friction against the piston rod.
OE all-weather fluid carries special additives to help handle extreme temperatures and reduce oil breakdown. Backed by Monroe's Limited Lifetime Warranty. Shocks work as a pair — replacing both sides together is recommended for balanced ride control; this listing is for one unit.
