TRE 4×4 TR100 air locking differential – rear axle
An open differential sends torque to the wheel with the least traction, which is why a single lifted wheel can stop a 4×4 completely. The TRE 4×4 TR100 air locker eliminates that: engage it on demand for 100% traction, disengage it and normal on-road manners return.

Check the TRE 4×4 locking differential catalogue and your axle type before ordering – fitment depends on spline count and crown wheel ratio, not model name alone.

What else you need
This locker is air actuated and requires the TRE 4×4 12V air compressor to operate. The same compressor can also be used to re-inflate tyres after airing down.
Installation
Fitting a locking differential means removing and re-shimming the differential, so it must be carried out by a specialist 4×4 workshop. Incorrect setup will damage the crown wheel and pinion. Supplied with a 12-month warranty.
