Truck forums are catching on to the specs game. My truck is rated to tow like 8200 pounds (3.21). If I had ordered it with the 3.92, that tow rating would have jumped by literally 3000 to around 11,200 pounds. It's magic I tell you! One little rear axle change that is only ever active from a dead stop and suddenly my truck can tow 3000 pounds more!! lol.
Never mind that once both trucks are moving in the city or passing semis up a grade, both trucks will have the same torque multiplication at the wheel because low and behold the transmission just sits one gear lower in the 3.21 for the same load/mph. But hey if you absolutely judge your towing experience by 0 to 10 mph then I guess you're going to be that much happier in a 3.92.
The reality is these new hurricanes will tow the same loads up to 10k pounds much easier than before, regardless of what any tow rating says, but the reliability/durabilty vs the v8 is yet to be discovered.
Lets also keep in mind that this is "max tow rating". Max tows are always unicorn trucks, and that means its a stripped down tradesman with 2wd. It's not yet clear to me if a feature-for-feature identical big horn or laramie is losing tow rating when comparing a 2024 hemi in that truck to an otherwise identical 2025 hurricane. So take a 2024 laramie/hemi with the 3.92, does it have more tow rating than a 2025 laramie SO with the 3.92? Or is it only the unicorn max tow (which is where the spec games are played) that has been reduced? Something we don't yet know at least to my knowledge (though I'd still bet cooling being the main factor which would affect all trucks across the board, not just the unicorn).
