Q & A

What's in the Box

Stock clutch hydraulic throwout bearing for stock-style 3-speed and 4-speed Chevy clutches only. Install simply by replacing one bolt from the front of the transmission with one of the provided studs, then shim to fit. Use 3/4" bore master cylinder.

This bearing is made much smaller than the racing version so that it will fit behind the "thicker" stock style clutches. This redesigned new housing is much cleaner as it has no boss on the body. Plus, this design also has a retainer on it to prevent over extension and seal damage.

Our T-5 throw out bearing is for GM-style Borg-Warner T-5 transmissions using an OEM or OEM replacement clutch. The base of the T-5 bearing is machined to fit the bearing retainer of the T-5 transmission. The compressed thickness is 1.516" and 2.065" fully extended giving .549" of travel. The inner diameter of the throw out bearing is 1.379".

It is known to fit many T-5 transmissions, but does not fit Ford versions. Use 3/4" bore clutch master cylinder.

Note: T/O bearing includes a 3/8" and 5/16" threaded retainer stud. If your T-5 makes use of a metric threaded front retainer bolt, to install this unit will require an installer to source a metric threaded stud or modified bolt as metric threaded hardware is not included.
