        • Includes Koyo bearings
        • Pinion seal included

        USA Standard differential bearing and seal kits include high-quality bearings and seals. Similar to a master install kit, but without shims (ideal if you are re-using your existing shims).

        Each bearing kit includes the following parts as-required: pinion seal, pinion nut, crush sleeve, gear marking compound, and a new gasket or RTV silicone – along with Koyo bearings and races. This kit is great for a lower mileage vehicle which can reuse the carrier bearing/races. These kits are also backed by a one year warranty to protect against any manufacture defects.

        USA standard gear and axle products are backed by a limited one-year warranty against manufacturer defects.


        Even though we recommend having your new gears installed by a shop, that doesn't mean you couldn't do it yourself. Gears can be tricky to install and may require tools that most people don't have lying around their garage. If you have any questions or would like additional information, please give us a call.
