Think about how you use your Jeep JK.
- Daily Driving vs. Off-Roading: If you drive your Jeep mostly on the street, an automatic locker might be fine. If you hit tough trails often, a selectable locker gives you more control.
- Trail Conditions: For muddy or rocky trails, lockers are a game-changer. They help you crawl over obstacles and climb steep hills.

Q: What is the difference between an automatic locker and a selectable locker?
