KYB Suspension Shock Absorber Mount P/N:SM5904
Cushion road impacts and cut the noise and vibration that a worn, hardened mount transmits into the cabin with the KYB Shock Absorber Mount (SM5890). It's a direct-fit rear upper mount for the 2016-2021 Mazda CX-3, 2013-2018 Mazda CX-5, 2018 Mazda CX-9, 2014-2018 Mazda 3, 2014 Mazda 3 Sport and 2014-2017 Mazda 6. See the Buyer's Guide tab for engine-level fitment.
This suspension shock absorber mount connects the top of the rear shock absorber to the vehicle body, locating the shock as the suspension cycles and isolating road-input vibration. Its superior rubber damps the noise, vibration and harshness that an old, hardened insulator would otherwise pass through.
Replacing the rear mounts as a pair is good practice for balanced ride quality.
