I have an '09 explorer with 4.0 l V6 engine and 3.55
axle ratio. It came standard with an auxiliary transmission cooler. It has a class 3 frame mounted hitch on it. However, it is rated to tow 3,500 lbs. The trailers I have been considering all have GRVW of around 3,500-4,000. I was looking at the Explorers with the same engine that are rated to 5,100 lbs and the only difference seems to be the rear
axle ratio is 3.73.
What would I have to do to my Explorer to modify it to be able to tow a little more? I would rather not have to buy a new vehicle and hoping I can make modifications to get me up to the 5,100 lb capacity.
Also, what else besides the 7 pt wiring do you need to do to make it tow ready?
Any thoughts & help is appreciated.
