Non-HD Tow to HD Tow Conversion

[ANDREW B PRICE]

Can a non-HD Tow pkg. Expy be modified to equal an HD Tow Expy? If so what needs to be changed, i.e. Trailer Brake Control module, add Trans. oil cooler. If there's more let me know.

I think this will depend largely on the model year. We have a 2017 non-HD (ecoboost) and we’ve added the brake controller, 7-pin, and tranny cooler. Some other years also required a different axle ratio to get you up to the HD tow capacities but not 2017. (Although I’ve never understood why.)

I still need to add sumo springs, before my first pull. But, feel confident I will be good with my

new Expy Max.
