Kyosho O-ring Medium RC Shock Seal - W5181-05

The Kyosho W5181-05 Shock Seal O-ring (M) is a genuine Kyosho spare part designed to maintain a proper fluid seal in RC car shock absorbers. Over time, shock seals wear out and allow oil to leak past the damper shaft, causing inconsistent suspension performance. Replacing the O-ring with a fresh Kyosho part restores the shock to its correct operating condition. This is a medium-size O-ring, so check your model's parts diagram to confirm KYOW5181-05 is the correct size for your specific shock assembly before ordering.
