Hey Emmanuel, thanks for reaching out!

The Atlas IV Double-Acting 10K Hydraulic Trailer Jack # ST74VR is what you're looking for. It comes with a connection kit that hooks up to and allows you to control the jack via your dump trailer controller.

This has a 4-bolt bracket as opposed to 3-bolt bracket that you currently have on your trailer, but you should only have to drill 1 set of additional holes per bracket as the bolt holes are spaced 2" apart on center.

Do you plan on doing this installation yourself, or having a shop take care of it for you?

Hi Jon thanks for the reply. I was looking at that setup but my issue would be the switch valve that would change between the dump cylinder and the jack. Since I would have 2 hydraulic jacks I would need to tie in both right?that would mean 8 ports? 2 each jack 2 dump cylinder 2 to the pump? unless there is another adapter I may need? Also I would be doing the install myself, I have installed a previously a single hydraulic jack on bumper pull. Thanks!

@EmmanuelS I should have known there were 2 jacks - I couldn't quite tell from the photo. For 2 jacks you'll need 2 of the Atlas IV Double-Acting Hydraulic Trailer Jack # ST73FR and the Hydraulic Dump Trailer Upgrade Kit # ST28FR which is for 2 jacks like what you have. We don't have all of this in a kit as of yet, but I imagine that will happen eventually.
