FAQ
What does the ACT RB813 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 RB813 confirmed to fit?
The RB813 fits the 1990-2005 Mazda Miata across its Base, LE, LS, M Edition, Mazdaspeed, SE, Shinsen, and STO trims, and the 1999 10th Anniversary Edition. See the Vehicle Applications list above to confirm the exact year, make, model, and trim.
