We manufacture all of our units to be used with factory hydraulics - this said, all of our setups can be used with aftermarket adjustable master cylinders as long as you do your part to make sure they're setup correctly - this especially applies to swap applications.

If you're using these make absolutely sure they are adjusted every time you install a new clutch, and that adjustment is checked on a regular basis - it's very easy to damage any clutch that is made with an aftermarket master cylinder assembly - not only is this the responsibility of the end user/installer, any damages caused by this are not covered under our warranty.

If you have any questions on adjustment procedures please submit a support ticket via the link on our support center and we'll go over this with you, in as much detail as necessary, to keep you from damaging your clutch.
