To ensure our customers receive all components with full integrity, we pack the motors separate from their linkage assemblies. This requires that the installer position and fasten the motor before continuing with the install. Please follow the instructions below and handle the assembly carefully.
CAUTION: Dropping the assembly or any excessive impact MAY cause damage to the motor.
Instructions:
- Position the gear cover in place as shown if not already in place.

Congratulations on your purchase of the genuine AMP Research PowerStep! Here’s what you should know…
POWER DEVOLOYABLE RUNNING BORAD OPERATION: AMP Research PowerStep running boards automatically move when the doors are opened to assist entering and exiting the vehicle.
Automatic power deploy:
The running boards will extend down and out when the doors are opened
Automatic power stow:
The running boards will return to the stowed position when the doors are
closed. There will be a 2-second delay before the running boards move to the
stowed position.
Automatic stop:
If an object is in the way of the moving running board, the running board will
automatically stop.
To reset, clear any obstruction, then simply open and close the door to resume
normal operation.
Manually set in the deployed (OUT) position for access to the roof:
The running boards can be manually set in the deployed position by firmly
holding the step down with your foot while at the same time closing the door.
To resume normal operation, open and close the door
Maintenance: In adverse conditions, debris such as mud, dirt, and salt may
become trapped in the running board mechanism, possibly leading to unwanted
noise. If this occurs, manually set the running boards to the deployed
position and flush the front and rear hinge arms with a high-pressure car wash
wand.
Avoid spraying the motors directly. After washing, apply silicone spray
lubricant to the hinge pivot pins. Do not apply silicone, wax or protectants
like Armor All® to the running board stepping surface. Caution! Keep hands
away when the running board is in motion.
