TRE 4×4 TR102 air locking differential – rear axle
The TRE 4×4 TR102 is an air-operated locking differential. Flick the switch and it locks both output shafts together, so both wheels on the axle turn at the same speed and full torque reaches the wheel that still has grip. Unlock it and the axle behaves exactly like the original open diff on the road.

- Fully open when off: no effect on steering, tyre wear or road manners
- Fast engagement: air actuation locks quickly and repeatably
- Built to last: manufactured from high-grade materials for heavy off-road loads

- Front and rear options available across most 4WD and 2WD axles
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.
