So, I'm looking to downgrade to a hemi from a cummins mainly for cost, etc. My payment would decrease significantly. I found three Laramie's that I am considering. Only one of them has the 4.10s though. I tow 2-3 times per week, less than 100 miles round trip each day and the weight is usually from 6,000-9,000 pounds. I would ideally like to level it and put on 35s or 295/60/20s.

I know that 4.10s are the better choice, but the two trucks with 3.73s are better equipped than the one with the 4.10s.

Do you think it would matter much if I just went with the 3.73s and put on 295/60/20s, leveled it and do towing thats well below the 14,000 lb threshold that they have?

Tough to say, my PW has 4:10s on the stock 33s, it pulls my camper that’s about 7500lbs super easy, I plan on going to 37s on it.
With that said with out doing all the math (comparing mine to what your looking at)you going to 35s would not be something I thing would be to bad as the 8sp has a real low first gear.
Lower gears are better though no question

Shoot my last truck had 3:21 gears with 35s and pulled the same camper easy as well. No mountains around here so can’t say about that. Lol

I had the same internal conundrum. I ended up with a Laramie loaded with a long box and 3.73s. Hard to replace options where as you can always regear.

ReGear is 1500-2000 minimum for parts and you do the work. Double to have it done. I specifically ordered 3:73. With tow haul, gear selectability and the power of the 6.4 it will pull fine. Going to 4:10s will up your RPM about 150 at 65 mph. You will not feel any difference off the line.

Does the hemi have a 6 or 8 speed (not sure what year you are looking at). Given that you are towing and going up to 35's I would definitely lean towards the 4:10 gears myself.

I've priced re-gearing and I'm getting close to $4000

As said, buy the better truck.
Gears are cheap and easy to do.

I had 3.73 in my 2500 and would pull anything with zero problems but i had teh V-10 too

I doubt there’s much difference towing between the 2 but I do really like my 4.10’s pulling 10-11K lbs.

If the one with the 4.10s wasn't 3 hours away, this would be an easy decision!

I went from a 3.73 in my old truck to a 4.10 in my power wagon. I can tell a difference between the two for sure especially the shifting pattern. The 4.10 seems to hold the gears a little better than the 3.73 and torque feels better. Is it a world of difference and a deal breaker I don’t think so but if I had the choice between two trucks that were identical other than gearing I would opt for the 4.10.

I've towed with both and I agree, the 4.10s just handle it better.

Ahh the great decision! I have a 13 2500 Laramie Cummins which came with the awful 3.42 gears. Been trying to make up my mind and debating gear choice for a couple years now lol! 3.92 would be perfect it they don't make em. I have 35s and a 9k RV that I tow occasionally. My gut tells me to do the 4.10s, I just worry about HWY rpm. Ive also considered a power wagon but but they only have a 9k max tow rating.
