Travel where you want without breaking the bank, or your vehicle.

Nitro Lunchbox Lockers are TOUGH - RELIABLE - AFFORDABLE. Not everyone needs or wants a selectable locker - Let Nitro Gear & Axle mechanical lockers upgrade your currently open differential! When it comes to performance & strength in an auto (mechanical) locker, our Lunchbox Locker units set the new standard.

Tech Note:

Picture is of a generic LunchBox Locker, parts included may vary depending on application.
LunchBox Lockers replace the internal spider gears of an open differential only, will not work inside limited slip carriers. Open, empty carrier cases sold separately.
