Does Rear End Gears Make a Huge Difference for Towing Capacity of Vehicle

Updated 04/16/2018 | Published 04/14/2018

Question:

Is the rear gear differential a big difference when towing a travel trailer ? If I add all the other needed accessories class 3 tow hitch, trans cooler, battery upgrade, brake control system, unknown about alternator was told it’s the middle 186 amp - I think of the 3 available for the vehicle. Manual says 3500 lbs w/out tow package 7200 with. Would I be safe towing a travel trailer 5000lbs with upgrades excluding rear differential ?

Rear end gears will make a huge difference for towing capacity. Higher numerical gears give additional leverage over the weight of the trailer so the impact "tow package" gears have cannot be understated at all really.

If you have the gears that mean you have a 3,500 towing capacity you'd have to stick with that unless you can contact Dodge about swapping gears.
