If you have the Warn Epic HyperLink then you might notice that they might rattle around causing scratches to your bumper. To help prevent this Warn brings you their HyperLink Isolators to protect your bumper from getting scratched and dinged up while you are driving. Made from polyurethane these isolators prevent your HyperLink from making direct contact with your Jeep’s bumper finish. Another great thing they do is prevent debris from damaging the pin shaft.
