Lunchbox Locker

The lunchbox locker gets its name from its small size. This style of locker is also commonly referred to as a drop-in-style locker due to fact that it drops inside of your open differential carrier to replace the stock spider gears. Two of the most common lunchbox lockers are the Lock-Right (left) and mini-spool (right). Since both of the shown traction aids reuse your existing open differential carrier, you don’t have to reset your differentials gear pattern. As long as you can follow instructions and have a decent tool set, you can install a drop-in-style locker in your driveway in a few hours.
