    I'm looking at a TT that weighs 6,876 lbs with a hitch weight of 890 lbs = 7,766

    I want to get a Dodge Ram 1500 with a 5.7L Hemi V8. The 3.55 axle has a max towing of 8,550 and the
    3.92 axle tows 10,050.

    I'm assuming I'll be better off with the 3.92. What's the difference in the axles that allows the 3.92 to tow more weight?

    Thanks so much for your help.

    If I remember correctly...the bigger rear end (3.92) gives you more pulling/towing power. Thus able to tow more weight. But, tradeoff is usually lower mpg. If truck is going to be used mostly for towing I would go with the 3.92.

    Lori It's all about gear to tire ratio. Same as a bycycle when you change size of sprockets.
