Assist Strap – Kia (85343-A9100BHH)

Assist Strap mounts inside the Kia door shell and takes the wear that repeated use puts on the door. Genuine Kia part number 85343-A9100BHH.

Water ingress past a failed seal corrodes the internal linkage, which is why the symptom appears suddenly after a wet season. Trim level affects whether the door carries a sensor, a soft-close or a keyless aerial, so confirm the original part number first.

Check the door alignment after fitting, as a worn part often masks a hinge that also needs adjustment.
