This spring maintains the proper tension in the seat adjuster system, ensuring that the seat slides and locks smoothly and holds securely in place. It helps prevent the seat from drifting or loosening under load.
Over time, the original spring may weaken, corrode, or lose tension, causing loose movement, poor locking, or rattling in the seat mechanism. Replacing it with a new OE-Match spring restores firm tension, stability, and smooth, precise seat adjustment.
