Your original master cylinder will not fit our Hydroboost systems. We highly recommend using one of the two master cylinders we supply. If you choose to buy your own master cylinder please call Van for applications that will fit your Hydroboost. Master cylinders for CJs and YJs will fit your existing brake lines, if you're buying for a TJ a line kit will be needed (sold below).

If you have any questions, give us a call at 800-256-6295.
