Only if you can find the proper 4-way actuator. They come with an 8-way square actuator.
On the instructions, they show a round one available for 4-way directional control.
You can ask around if anybody may have some or you could experiment with a lathe, but it may not be worth the effort. These are great ultra rugged joysticks for 8-way action and I like them a LOT!
