This shim, if needed with your setup, is made here in this USA of .180" thick steel.  Will not fit Cadillac CTS-V.  Also sold as part of a convenient three pack, here: Tick Performance Slave Cylinder Shim Kit (3 Pack)

How to determine if a shim is needed for your setup:

During each and every clutch install you perform on a newer GM vehicle, you must measure to see if a shim is necessary for proper installation. This is done by taking two simple measurements (see worksheet):

1)  Measurement "A" is the distance between the surface of the bellhousing that meets the transmission to the tip of the pressure plate fingers. To get an accurate measurement, the clutch must be torqued properly.

2)  Measurement "B" is the distance between the throwout bearing surface to the transmission surface that meets the bellhousing. To get an accurate measurement, the slave spring must be removed and the bearing must be fully seated at the bottom of it's travel; resting on the slave's base.

Once you've got your two measurements, make sure that measurement "B" is ~1/16" to 1/8" LESS than measurement "A". If you come up with more than 1/8", add an appropriately sized shim between the slave cylinder and the transmission in order to get the measurements where they need to be.

Your “A minus B” measurement should be 0.125 to 0.200 for adequate bearing travel and to allow for clutch wear. If there is no difference between the two measurements, or if "B" is greater than "A", there could be a problem with clutch engagement which could result in premature clutch slip and eventually a total failure. Contact your clutch manufacturer before proceeding with the install.

    Did what they were designed to do, space out the throwout bearing.

    Good quality. My only complaint is that I paid for overnight shipping and didn't receive for 2 days. The item didn't get shipped until the next day after order which kinda defeated the purpose.
