The ER4 electric reverse drives a 12DP 92 tooth ring gear which fits to your chain drive differential to the right side of your differential sprocket.
The geared, 1.7kW, 12V electric motor has solenoid activation for the mechanical engagement of the drive gear to the ring gear.

These units will fit most of our chain drive units and ring gears can also be manufactured to suit other units such as the Quaife QDF7ZR.

** The ER4 electric reverse unit is designed for use on vehicles up to 550kg mass.
The ER4 reverse is for use on low gradients on paved surfaces.
On board battery capacity must be sufficient to power the 1.7kW motor on load.

Note: Sliding plate and pivot mounts are designed for use with our standard side mount bearing carriers.
These bearing carriers are available for Quaife QDF7ZR, IB5 and MX5 chain drive units.

The ER4 electric reverse cannot be fitted to any of our chain drive units which have inboard disc rotors as the motor would foul the rotors.
We can supply other electric reverse units which can be positioned remotely from the differential.
