NITRO Lunch Box Lockers

NITRO Lunchbox Lockers

Nitro's Lunch Box Lockers are fully automatic. When the wheels need to differentiate in a turn (the outside wheel needs to rotate faster to complete the turn) the internal gears on the Lunch Box Locker will remain locked under acceleration. For the gears to overrun each other and allow this differentiation the vehicle must be turning and decelerating naturally. Any load created by acceleration will automatically lock the Lunch box Locker again.


Check them all out below:

Lunch Box Lockers replace the internal spider gears of an open differential only, they will not work inside limited slip carriers. If you have a limited slip and are interested in a lunchbox locker contact us, we have open carriers for most axle applications available.

I have a 2000 Cherokee XJ with a Spartan "lunch box locker" (no affiliation) and it's been in my front axle Dana 30 and has served me well. I did add chromolly drive shafts to handle the extra torque. I drive it 80 miles round trip as a DD. With over 40k miles on it and challenging terrain when I can get out and work it...it's unbelievable. I' have been through just about everywhere in So Cal from mild to wild and holy crap this just keeps pulling! FYI...no locker in the back (8.25 stocker). it does make it's clicking noise on turns but I'm so used to it I don't even notice. If you you ask me, that lets me know it's ready to lock out as req'd...if i don'y hear it it's a problem.

Whats the difference between a Mechanical Locker and a Selectable Locker?


Mechanical Lockers:
(Detroit, NITRO Lunch Box, Powertrax, Lock Right)
Mechanical lockers engage automatically when force is applied to the differential via the pinion and ring gear. While force is not actively being applied, springs in the locker allow the mechanism to disengage. That is to say that when you press on the gas it locks up, when you let off the gas and turn it unlocks.
Mechanical lockers are well know for the popping and clanking noises they make when engaging and disengaging.
Mechanical lockers can be installed in front differentials but you must have lock out hubs and they MUST be unlocked for on-road driving because of steering issues.


Selectable Locker:
(ARB, TJM, OX, Auburn ECTED, Eaton E-Locker)
Selectable lockers fall into 3 categories - air, electric and manual.
Air lockers use compressed air from a vehicle-mounted air compressor to engage the locking mechanism.
Electric lockers use an electrical pulse to engage a magnetic locking device.
Manual lockers (OX) must be engaged by pulling a cord, usually requiring the driver to exit the vehicle (although many OX can be upgraded to electric).
Air and electric lockers can be activated by a switch inside the vehicle.
Selectable lockers are fully locked when engaged and function as an open differential when not engaged.
Some electric lockers function as a limited-slip differential when not engaged.
