KYB Suspension Strut Mount Kit P/N:SM5471
Quiet the clunks and smooth out your steering with the KYB Suspension Strut Mount Kit SM5924, a front strut mount and bearing assembly that drops in as a direct-fit replacement for the 2015-2019 Hyundai Sonata, 2016-2020 Kia Optima, and 2017-2020 Kia Sportage (see the Buyer's Guide tab for engine-level fitment). As the top mounting point for the front strut, it cushions road impacts and — thanks to its integrated bearing — serves as the steering pivot while supporting vehicle weight, so it plays a direct role in steering feel and front-end alignment.
If worn front strut mounts are the cause of your steering vibration, noise, or memory-steer, this KYB kit replaces them.
