TRE4X4 Air Locker Differential – Suzuki 26 Spline 10 Bolt
Maximum traction for your Suzuki off-road vehicle
When the terrain gets truly challenging, a standard differential is no longer enough — you need total control.
The TRE4X4 Air Locker is designed for those who use their Suzuki seriously off-road. Deep mud, rocks, extreme articulation, or steep climbs are no longer a limitation: with a simple switch, you can transform your axle’s performance and deliver full traction to both wheels.
On the road, it remains smooth, quiet, and unobtrusive. But when needed, it engages instantly, locking the differential 100% and allowing you to keep moving where you would normally get stuck.
Fitment
- Suzuki Samurai – Santana – SJ – 26 spline, 10 bolt rear
- Suzuki Jimny – 26 spline, 10 bolt rear
- Suzuki Vitara 1988–1998 – 26 spline, 10 bolt front
Full control, when you need it
Unlike automatic lockers or limited-slip differentials, this system gives you complete control: you decide when to engage it and when to return to normal driving.
The result is more precise handling in technical sections, increased safety, and the ability to fully exploit your Suzuki’s off-road potential.
How it works
The system uses compressed air to activate an internal mechanism that fully locks the differential:
- Normal mode → open differential (road use)
- Active mode → locked wheels (maximum traction)
Result: zero traction loss, even in the most extreme conditions.
