      when I get this installed will I have to get everything re-geared or could I just leave everything alone?

      • Hello, You can run a locker with stock gears. This being said if upgrading tires to a larger size it is recommended to do a re-gear.

      Will this work with automatic transmission

      • Hi, This Yukon Gear Grizzly Locker is designed for use in 30 spline, Dana 44 rear axles found on 2007-2018 Jeep Wrangler non-Rubicon JK Models, excluding 2012-2018 automatic transmission models. So unfortunately this would not work with an automatic transmission.
