Door lock bouncing up and down? Finding it increasingly difficult to lock your Mercedes?
The Springs within the door lock actuator mechanisms deteriorate over time, the OEM spring is made from cheap metal which wears quickly, this wear leads to the symptoms noted above.
Simply install our improved design replacement springs and restore your locks for good.
Made from high quality Stainless Steel (will not deteriorate over time like springs offered by some others) our improved design thicker wound springs will restore your lock and will not deteriorate over time like the OEM part does, save the cost of a replacement actuator that will just fail again.
