ET128 Electric Differential Locker: Electric On-Demand Locking for 4x4 and Off-Road Vehicles

Chonghong is pleased to introduce the ET128 Electric Differential Locker (E-Locker), an electrically actuated differential locking solution engineered for 4x4, SUV, and off-road vehicles. The ET128 uses an electric actuator to control differential lock engagement, helping to improve torque distribution between the left and right wheels whenever extra traction is required across demanding terrain such as mud, sand, rocky surfaces, and steep inclines.

Key Features

• Electric engagement — Convenient push-button electric control replaces manual or air-operated locking systems.
• On-demand locking — The driver engages the locker only when additional traction is needed, preserving normal on-road handling when unlocked.
• Improved traction — Helps transfer drive torque to the wheel with grip, reducing the chance of a single wheel spinning freely.
• Durable mechanical locking structure — A robust mechanical lock built to withstand the repeated loads and impacts of serious off-road use.
• 4x4 / off-road application — Ideal for SUVs, pickup trucks, and 4WD vehicles used in off-road and overlanding scenarios.
• Aftermarket-ready — Suitable for the automotive aftermarket, performance, and vehicle modification markets.
• Vehicle compatibility matching — Matched by vehicle model, year, axle type, gear ratio, and spline count to ensure correct fitment.
• OEM / wholesale supply — Available for bulk purchase and international supply to distributors, importers, and equipment manufacturers.

Typical Applications

Why Choose the ET128 Electric Differential Locker?

The ET128's electric engagement system offers a fast, reliable, and driver-friendly alternative to traditional locking differentials. When traction is lost on one side, activating the locker equalizes wheel speed and channels drive torque to the wheel with the most grip, helping the vehicle maintain forward progress. Its durable mechanical locking structure is engineered for the repeated loads and impacts encountered in genuine off-road environments.

As an on-demand locking solution, the ET128 keeps the vehicle's normal on-road driving characteristics fully intact when disengaged, making it a practical upgrade for daily-driven 4x4 and SUV owners who also need dependable off-road performance on weekends and overland journeys.
