    Maximum Traction and Differential Case Life. When you’re tackling the most challenging road and off-road conditions in your Wrangler, you need the maximum traction. The Spartan Locker for Dana 30 Differential from USA Standard Gear is an automatic differential locker that is a super-easy installation. It’s built super-tough and its automatic locking means all power goes to the wheel that can use it, while reducing the driveline stresses that normally lead to premature failure of components like the differential case.

    Superior Automatic Operation. The Spartan Locker is designed for easy fit-and-forget operation. Made from 9310 steel, it is a super-rugged and reliable design that handles all differential locking automatically, so there’s no added complexity to installation or operation to worry about.

    Easy DIY Installation. The Spartan Locker doesn’t use the thrust washers, but it does have an innovative spring-and-pin design, making it super-easy to install. NOTE: for use with non-Rubicon JK Wrangler front differentials, carrier case (#YC D706008, sold separately) is also required.

    One-Year Limited Warranty. USA Standard Gear provides a 1-year limited warranty against manufacturer’s defects.

    Application. The USA Standard Gear Spartan Locker for Dana 30 Differential fits the 1987-2018 YJ, TJ, and JK Jeep Wrangler.

        I have a 2013 Jeep Wrangler Unlimited Oscar Mike edition. I want this locker for my front end. Is this the only thing that I need to buy to lock my front axle or do I need to buy more stuff to do so?

        • This is the only component required, other than replacing parts that are typically replaced when removing the diff, such as carrier bearings, cover gasket, etc.

        Will this locker fit in a 3.07 geared carrier? I know most lockers for TJ's require the larger 3.73 carrier size.

        • This will require a 3.73 and larger carrier.
