KYB Suspension Shock Absorber Mount P/N:SM5919
$105.99

Help quiet a noisy, harsh-riding rear suspension with the KYB Shock Absorber Mount (SM5919), a direct-fit replacement for the listed applications. It fits many vehicles, among them the 2018-2019 GMC Acadia, 2019-2021 Chevrolet Blazer and 2017-2021 Cadillac XT5; see the Buyer's Guide tab for the full list. This rear upper suspension shock absorber mount secures the top of the shock to the body and cushions the impacts from road bumps that old, hardened insulators otherwise pass straight into the cabin.

  • OE-quality replacement: built as an Original Equipment quality component designed for each listed application.
  • Superior rubber: the mount's rubber isolator is engineered to reduce noise, vibration and harshness.
  • Cushions road impacts: softens the jarring, noise and vibration that worn mounts transmit into the vehicle.
  • Matched-grade hardware: supplied with matched grade studs and nuts.

As the rubber in a shock mount ages and hardens, it can pass more knock, vibration and harshness into the body. If a worn rear upper mount is the cause of added noise or a clunk over bumps, this KYB unit replaces it. Diagnose the cause before replacing, and because mounts wear at a similar rate, it is good practice to service both sides together as a matched pair.

What are the signs my shock mount may need replacing?

Knocking or clunking from the rear over bumps, plus added noise, vibration or harshness, can be signs of worn, hardened mount rubber. Diagnose the cause before replacing, since other parts can share these symptoms.

Does this mount include mounting hardware?

KYB supplies matched grade studs and nuts with this mount. Consult the vehicle service information for the correct torque and whether any fasteners may be reused.

Should I replace both rear mounts at the same time?
