KYB Suspension Shock Absorber Mount P/N:SM5887
Soften harsh road impacts and quiet the clunks and rattles with the KYB Shock Absorber Mount SM5939. It installs as a rear upper direct-fit replacement for the 2018-2021 Mazda 6, 2019-2025 Mazda CX-5, and 2019-2023 Mazda CX-9, offering OE-quality replacement designed for each application. As a rear upper suspension shock absorber mount, it secures the top of the shock to the body and isolates the suspension, cushioning bump impacts to reduce the jarring, noise, and vibration that old, hardened insulators transmit into the vehicle.
Signs your mount may need replacing include added noise, vibration, or knocking over bumps as the rubber hardens or separates. If a failed mount is the cause of those symptoms, this replaces it. Mounts install as a left/right pair — this listing is for one, so order two for a complete rear replacement.
