FAQ
What does the ACT RB105 release bearing do?
It rides against the pressure plate fingers or diaphragm and slides on the transmission input shaft, engaging and disengaging the clutch each time the pedal is pressed.
Is this a direct-fit, OE-style replacement?
Yes, the release bearing meets or exceeds OE standards and is a direct-fit replacement for the factory unit.
Should the release bearing be replaced whenever a clutch kit is installed?
Yes, ACT recommends replacing the release bearing at the same time as the clutch disc and pressure plate, since it is a wear item that is difficult to access again without removing the transmission.
What vehicles is the RB105 confirmed to fit?
The RB105 fits the 2000-2009 Honda S2000 Base and the 2008-2009 Honda S2000 CR. See the Vehicle Applications list above to confirm the exact year, make, model, and trim.
