Description
Off-road Factory Race Series bump stops were developed with top off-road racing teams to provide precise control of the last few inches of suspension travel. By applying our race-proven damping technology in a purpose-built, stand-alone component, you can use every bit of suspension travel without harsh bottoming.
The built-in FOX Air Valve (FAV) Valve allows precise nitrogen charge adjustments to provide a wide range of bottoming control. The durable construction and replaceable strike pad are built to take the abuse while providing predictable and quiet operation.
