Electric Over Hydraulic Actuator Setup Recommendation for Converting EZ Loader Boat Trailer

Question

Question:

Will kit HS381-9067 be all I need to convert my surge disc brakes to EOH? Vehicle is a Ford Expedition 2018 with factory brake controller and 7 pin tow kit. Trailer is tandem 7k ez loader boat trailer with Titan 225 disc brakes on both axles and a Titan 60 actuator. Is this the correct set of parts to get the job done or will additional mounting plates or hardware be needed? Thank you!

Yes, the HydraStar Marine Electric Over Hydraulic Actuator w/ Breakaway and 7-Way RV Harness # HS381-9067 is the exact kit you'd want/need to convert you surge disc brakes to electric over hydraulic. This includes everything you'd need and also has the best actuator out there. We prefer it because it has the fastest reaction speed and is the most reliable.

The factory brake controller of your 2018 Expedition is perfectly compatible with this as well.
