Stopper Bush Absorber Rear > HYUNDAI TUCSON IX35 / SONATA YF / KIA OPTIMA K5 / SPORTAGE SL > 55348-3W000 > GENUINE PART

This is a Genuine OEM Rear Shock Absorber Bump Stop, identified by the part number 55348-3W000. This component is a standardized part used across several popular Hyundai and Kia platforms from the early 2010s, including the compact SUVs Hyundai Tucson (IX35) and Kia Sportage (SL), and the mid-size sedans Hyundai Sonata (YF) and Kia Optima (K5).

The Stopper Bush (or bump stop) is a critical safety component. It is engineered to absorb the final, high-energy impact when the suspension is fully compressed due to heavy loads or severe road imperfections. This progressive cushioning action prevents harsh, damaging metal-on-metal contact, thereby protecting the internal components of the rear shock absorbers.

Replacing an old, brittle, or cracked bump stop with the Genuine Part ensures:

✔ Broad Vehicle Compatibility: Guarantees correct fitment and optimal energy absorption across these specified models.

✔ Shock Absorber Protection: Prevents internal damage and prolongs the service life of the rear shocks.

✔ Controlled Ride: Maintains the intended cushioning effect during severe impacts, contributing to stable handling and ride comfort.
