Help restore controlled, composed damping with the Monroe OESpectrum Rear Suspension Shock Absorber 5540 — a 2014-2018 Mazda 3 shock absorber designed to bring back factory ride feel. It installs as a direct-fit rear replacement for the 2014-2018 Mazda 3 (see the "Vehicles it fits" section for engine-level detail).
The OESpectrum design is tuned to filter out noise, vibration and harshness while delivering precise handling and control on the listed applications.
- Full displaced valving: tuned to the vehicle and paired with a larger bore for more efficient damping and a smooth, consistent ride over road extremes.
- 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 for improved ride and handling.
- OE all-weather fluid: contains special additives to assist with extreme temperatures and help reduce oil breakdown, while a self-lubricating fluid seal retains gas and reduces friction against the piston rod.
Shocks work as a pair, so replacing both rear units together is best practice for balanced ride control. Backed by Monroe's Limited Lifetime Warranty and Feel the Difference Guarantee.
