Description
The pinion o-ring is a critical seal component in your Ford 9-inch rear end that prevents gear oil from leaking past the pinion shaft. Over time, factory o-rings degrade from heat cycles and pressure, leading to fluid loss and potential differential damage. Installing a fresh o-ring during maintenance or rebuild ensures a tight seal and protects your investment in quality differential components.
