Aubirn Electric Locker Ected Locking Differential

SELECT-A-LOC Electric Locking Differential

Most Auburn SELECT-A-LOC models offer both “limited-slip” and “locker” modes. Some of the newer units switch from “Open” to “Lock”


An on/off switch is mounted near the driver. In the “off” position it operates in limited-slip mode. When the “on” position is selected, the differential operates as a solid axle assembly – the spool/locker performance you desire at the strip or off-road.

SELECT-A-LOC™ Advantages:

  • SELECT-A-LOC gearing is made from aircraft quality, 9310 heat-treated billet steel to make it as tough as nails!
  • SELECT-A-LOC can be switched on or off “on the fly,” at any road speed.
  • SELECT-A-LOC does not have any shift forks or pins that must be lined up to obtain locker mode.
  • SELECT-A-LOC is quiet – say good-bye to noisy lockers!
  • SELECT-A-LOC is backed by an industry-leading one-year warranty, just like all Auburn Gear Performance Differentials.
  • SELECT-A-LOC is backed by the industry-exclusive program. D-REX = Differential – Replacement EXchange Program.
  • SELECT-A-LOC can be used in front axle applications – with or without lockout hubs.
  • SELECT-A-LOC is the only selectable locker that offers both limited slip and locker modes. Forget the rest – go with the best!

Important Note: The SELECT-A-LOC is not recommended for use in front axles that feature an “Inter-Axle Disconnect.”
