I am trying to increase the towing capacity of my 2002 Durango SLT 4.7L w/3.55 gear ratio in the rear and 105mm in the front. It came with a class IV hitch and controls for a trailer w/electric brakes. I would like to be able to tow a 20 ft enclosed auto hauler with a 3000 lb vehicle inside.

 

Welcome to DF I'll move this thread to the Durango section.

 

We were actually just talking about this the other day. Here is the thread that had a bunch of that information in it. https://dodgeforum.com/forum/1st-gen...uy-pickup.html
