KYB Suspension Shock Absorber Mount P/N:SM5850

$45.99

Description

Quiet the harsh, rattling ride of worn rubber and keep the rear shock absorber firmly located with the KYB Shock Absorber Mount SM5850. This rear upper suspension shock absorber mount installs as a direct-fit replacement for the listed applications and fits many vehicles, among them the 2011-2019 Hyundai Sonata, 2011-2020 Kia Optima, and 2010-2015 Hyundai Tucson.

KYB shock mounts replace the old, hardened vibration insulators that let road noise and harshness pass into the cabin. By cushioning the impacts from road bumps, this mount helps reduce the jarring, noise, and vibration that a tired mount transmits into the vehicle.

OE-quality replacement: designed for each application to help restore proper suspension performance.
Superior rubber: reduces noise, vibration, and harshness from a hardened, worn-out mount.
Matched grade studs and nuts: included for a secure installation.

If a worn or deteriorated mount is the source of clunking or excess vibration from the rear, this KYB unit replaces it. See the "Vehicles it fits" section for the full engine-level fitment.

Frequently Asked Questions

What is the KYB SM5850?

It's a rear upper shock absorber mount. It secures the rear shock absorber to the body and uses superior rubber to isolate road noise, vibration, and harshness from the cabin.

Which vehicles does the SM5850 fit?

It fits several Hyundai and Kia models, including the 2011-2019 Hyundai Sonata, 2011-2020 Kia Optima, and 2010-2015 Hyundai Tucson. See the "Vehicles it fits" section for the complete year-make-model list.

Does it come with mounting hardware?

Yes. This KYB mount includes matched grade studs and nuts for the installation.

What are signs my shock absorber mount needs replacing?

Common signs include increased road noise, vibration, and harshness reaching the cabin, or clunking from the rear as the rubber insulator hardens or deteriorates. Diagnose the cause before replacing.

Should I replace the mounts on both sides?

It's good practice to inspect and, if needed, replace the mount on the opposite side at the same time, since both corners typically wear at a similar rate and perform more evenly as a pair.
