This RockShox Rear Shock DU Bushing Removal Tool is used to easily remove and press out metal DU bushings from any brand of shock. DU bushings are pre installed in RockShox shocks. Skip the frustration while trying to use sockets to remove your DU bushing, and snag this tool. We promise this tool will be well utilized in your home shop, and you can most likely rent it out to friends in trade for beers or burritos! Once pressed out, you can then install mounting hardware with IGUS bushings most commonly seen with Fox Mounting Hardware. You can also use this to remove all of the RockShox Mounting Hardware from your RockShox, and install it into any other shock with a 1/2" eyelet (which is basically every modern shock model out there).
