Jeep Lockers & Limited Slips - Choose from air lockers by ARB, Detroit Lockers, Powertrax No Slip lockers, electric and cable lockers, universal limited slip parts and rebuild kits for all Jeeps.
For all situations except factory OEM electric lockers, a standard open carrier can be replaced with a limited slip or locker. Likewise, a locker or limited slip can be replaced with a standard open carrier. Limited slips and lockers can be interchanged. And of coarse, a spool can be installed in place of all of them. The main point is that the differential carrier unit design is independent of the housing it is being installed into.

Transmits equal torque to both wheels when driving straight ahead. However when one wheel spins due to loss of traction, a patch of ice, mud, too much throttle, etc., the unit automatically provides more torque to the wheel that has traction. Recommended for daily driving, works well in ice, rain, mud and snow. However, in situations where absolute lockup is needed, a limited slip is not the best choice due to the fact that limited slips do slip in some situations.
Positraction is a type of limited slip and is a term that is used very loosely as another name or description for limited slip differentials. A positraction is not more aggressive than a limited slip or vice versa. The name "positraction" was used by General Motors for their limited slip differential and the name has been associated with limited slips for many years.
Automatic Lockers:
Detroit, Lock Right, Powertrax No-Slip
Lockers, mechanical locking differentials that is, provide 100% transfer of power to both drive wheels. This power can be lost if both wheels spin, but a locking differential will never let one wheel spin free by itself while the other one sits still (unless the unit is broken). Automatic locking differentials are engineered to keep both wheels in a constant drive mode, yet have the ability to unlock to permit a difference in wheel speed while negotiating turns.
On-Command Lockers:
Electrac, OX Lockers, ARB Air Lockers
Many people want the benefits of a locking differential, but do not want the handling characteristics or noise of an automatic locker. There are a few on-command lockers available as an OEM option. These include the 1998 & newer Toyota Tacoma & Land Cruiser. These EOM designs use an electric motor or vacuum diaphragm to engage the locker. When it is not engaged the unit acts like a standard open differential with no ill side effects aside from poor traction. When engaged, these units' lockup 100% and act like a spool with no differential action or difference in speed between the left and right wheels allowed. |
