Stopper Bush Absorber Front > HYUNDAI SONATA LF 2016 / KIA OPTIMA K5 GT > 54626-C1050 > GENUINE PART

This is a Genuine OEM Front Shock Absorber Bump Stop, identified by the part number 54626-C1050. This component is critical for the front suspension system of the seventh-generation Hyundai Sonata (LF chassis), common around the 2016 model year, and performance variants like the Kia Optima K5 GT (JF chassis). The specific part number often denotes a particular length or density of the bump stop, tailored to the vehicle's engine size, trim level, or suspension tuning (e.g., sport suspension).

The Stopper Bush (or bump stop) is made of a durable, energy-absorbing material. It is fitted onto the strut piston rod and acts as a progressive cushion, absorbing the final, high-force energy when the suspension is fully compressed (e.g., hard braking or severe road impacts). This action prevents harsh, damaging metal-on-metal contact (bottoming out).

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

✔ Direct Fit: Guarantees correct fitment and optimal energy absorption characteristics for the specified Sonata and Optima models.

✔ Strut Protection: Prevents internal damage and prolongs the service life of the front struts.

✔ Ride Consistency: Provides controlled compression, maintaining stable handling and ride comfort, especially crucial in performance-tuned models.
