Automatic Lockers

Upgrade your 1986-1997 Nissan Hardbody D21 with an automatic locking differential for improved off-road traction without the need for switches, air lines, compressors, or manual engagement. An automatic locker works mechanically, engaging when additional traction is needed to help keep both drive wheels moving through rocks, loose dirt, mud, sand, and other challenging terrain.

Some Nissan Hardbody automatic lockers are commonly referred to as lunchbox lockers because they install into the factory differential carrier rather than replacing the entire carrier assembly. Depending on the application, this can make installation simpler and more affordable for experienced DIY mechanics.
