The TrueTrac performs like a limited-slip differential under normal driving conditions, automatically transferring torque to the wheel with better traction when ground conditions warrant.

Created to provide traction on demand, without sacrificing highway driving performance, ARB Air Locker differentials employ an air source (sold separately) to pneumatically operate a solid and durable locking mechanism inside the differential.

The ELocker is an electronic, selectable differential for drivers that want full control and traction on demand.
