If you have a power steering leak between your master cylinder and your hydroboost this seal is exactly what you need to repair it. The repair can be done by almost anyone by following the repair video below. Typically these leaks are not actually your power steering pump or reservoir, instead just this cheap seal! This seal is MADE IN THE U.S.A. and comes with FREE USPS SHIPPING WITH TRACKING.

These repairs require a special socket which most people do not have. If you don't know if you have the socket we will include a brand new socket so you can ensure you have the right tools to get the job done.

FAQ

If your leak is between the master cylinder and the hydroboost the circular seal is the issue. If your leak is from the middle of the hydroboost, the figure 8 seal is your issue.

We always recommend replacing both seals during any repair as it is likely both seals are worn and they could be damaged during dis-assembly & re-assembly.

These seals are proudly made in the United States.

There are two variations of the piston seal, so if your vehicle is not listed then the manufacturer likely changed the piston seal variant used throughout the build of the vehicle. You can select "Vehicle Not Listed (But Has Hydroboost)" and that kit will include both variations of the piston seals. You will not use one of the piston seals, however if you select that option you will be sure to have the correct size piston seal.

The "Vehicle Not Listed (But Has Hydroboost)" will fit ALL hydroboost units.

Yes, we offer various different shipping methods including 1 day service. Rates are calculated and displayed at checkout.

Hydro what?

Now I know what a hydroboost is, how to rebuild it and why replacing my PS pump and both lines didn't stop that PS leak. Now that I know better, wrapping a plastic bag around the hysdroboost and driving for a few days will confirm if it's leaking.
