A clock spring is a coiled ribbon of wire mounted behind the steering wheel that maintains an electrical connection to the airbag, horn, and steering-wheel-mounted controls while still allowing the wheel to turn freely, lock to lock. A worn or broken clock spring commonly triggers an airbag warning light, a horn that stops working, cruise control or radio buttons that won't respond, or in more serious cases, an airbag that won't deploy in a collision. Browse replacement clock springs for cars, trucks, and SUVs to restore a safe, reliable connection through the steering column.
