- '05 Explorer XLT
Hi all. I have an '05 Automaric Ford Explorer V6 with a gear ratio of 3.55. The owners manual puts the max trailer at 3,380. The max trailer for a gear ratio of 3.73 is 5,380. The only difference I can see is under the engine section which lists that the 3.55 comes with a class II towing, while the 3.73 comes with a class III/IV towing.
My understanding is that the difference in towing between a 3.55 and a 3.73, all else being equal, is about 5% ( [3.73 - 3.55] / 3.55 ). So, why is there such a big difference according to the manual?
Thanks in advance for your help.
