FPS 805-00-066-KIT Fox Shock 2.5" Internal Floating Reservoir Piston With Bleeder Screw Hole

Get rid of cavitation air bubbles in your shocks. Especially on piggyback coil overs or internal and external bypass shocks, where you can't flip the reservoir upside down to bleed it while filling the shock body with oil.

On some of the new style buggy, truck and UTV Fox shocks, they have a bleeder screw in the center of the piston to eliminate any air pocket underneath it. Because of that bleeder screw, you can no longer use a conventional 1/4"-20 thread IFP tool to set the depth or remove the piston. Instead, there's a special tool that sits on top of the piston and you turn the tool a quarter turn to grab onto the piston.
