"Icon Vehicle Dynamics offers a re-building service for our entire 2.5” line of shocks. The basic re-build service includes labor, new seals and new shock oil and runs $125.00 per shock. If other parts such as bearings, shafts, and charge ports need to be replaced an Icon representative will call you and let you know the additional costs of these items. Listed below is the procedure for sending in your shocks for a re-build."
