The TRE E-Locking Differential is designed to take you to the destinations others can only dream about. 

This E-locker is electromagneticly operated for ultimate reliability. Like all modern factory OEM lockers, it is engaged electrically with the push of a button- no air lines under your vehicle, no air compressor, and no air seals inside the locker to worry about.

When needed, the driver presses the cabin switch, sending power to the e-locker and energizing the electromagnet, causing it to slide over and mechanically lock both axles together to send torque equally to both sides.

The TRE E-Locker is equipped with an improved clutch gear design whose locking depth has been increased from 2mm, as found in some competitor's lockers, to 5mm. This improved design fundamentally solves the problem of automatic unlocking that has affected other E-Lockers. Additionally, the gear is nickel-plated making it rust-proof and greatly improving the degree of wear resistance, service life, and locking efficiency.

The TRE Wave Spring makes locking and unlocking more stable and reliable because the wave spring fits tight radial and axial spaces better. Additionally, the Wave Spring reduces the spring height by 50% compared to ordinary coil springs so there is no need to drill the spring holes deep into the clutch gear, thus increasing the stength of the clutch gear.


  • Provides 100% traction on demand without affecting on road drivability or driveline wear
  • Vastly improved traction means less reliance on momentum, which reduces the likelihood of vehicle damage and environmental impact
  • Easy, convenient operation allows the user to concentrate on the terrain without leaving the comfort and safety of the driver’s seat
  • Ultra durable and extremely strong - only the highest quality materials used in construction. 
  • Incredibly simple yet effective design that employs minimal moving parts, thereby ensuring maximum reliability.
  • Thoroughly tested and proven design – we know of many Monteros in the USA who have been using TRE lockers for years and we have yet to hear of a single failure.
  • Can be used in any transfer case setting - 4WD, AWD, 2WD.
