Would you rather have 3.21 + LSD or 3.92 w/o LSD?

[QwikKota]

It's really down to just the gearing and the LSD for me. I just don't know which combo to choose. I'm good with everything else. Don't need the 3.92 at all -- I'll never be towing or lifting my Ram. But, it seems from the forum that they're awesome to drive. Although it doesn't have the LSD, it's $2,300 cheaper than the other model.

On the flip side, the other one is more expensive and "slower", but has the LSD. Decisions decisions!

I would get the 3.92 truck. Why is it so much cheaper, different trim? I missed the part where you have snow and I am guessing you are looking at 4x4 trucks. If you swap from 3.21 to 3.92 later on a 4x4 you would need to buy a new front diff at $1200 or something crazy.

It has a few less options that mean nothing to me. No sunroof, no tow mirrors. Can't think of anything else that's different. And yes, it is a 4x4.

Sunroofs leak and tow mirrors are gigantic and if you really need them can be added later. Go get it! Do they still offer 0% financing? Hopefully it's a Hemi.

It's a Hemi. The dealer claims they can't, no way possible, give me the 0% financing and the truck at $36,000 -- it's one or the other. If I want the 0% then they said the price will go up by at least $4,000. Sales ploy? I don't know. But I won't be a sucker. I'm going to negotiate with all I have for that 0%.

These offers are for Texas, pretty good. In May I got 0% and 1500 off plus $3500 in rebates due to owning a Dodge and something else. That and money off the truck. These are model specific. I would get the VIN and call the Chrysler Incentives department to get the real facts.

Do you mostly drive on the highway? If so, the 3.21 will benefit you with some gas savings. Accelerating above ~60mph, engine power and vehicle drag matter more than gearing (passing slow drivers on the highway). 0-60'ish sprints the gearing is more important. Just depends on what you're realistically going to do with the vehicle.

I extensively drove identical 2014's, one with 3.21, the other with 3.92, and I went with the 3.92. For ME, everything about 3.92 was better. I don't sit on the highway forever at 80mph. Highway speed limits around me are 55, and occasionally 60mph. Plus traffic is bad, so actually cruising at 60-65mph is rare (unless it's late night/early morning), and I've wasted enough $$ on tickets for 15-30mph over the speed limit in my teens and 20's. (knock on wood) I never get caught sprinting to 60+mph... I always got caught on cruise control...

So anyways, This is very much a personal preference to determine which axle ratio is better. Both axle ratios serve a purpose. The fuel mileage difference is irrelevant at the speeds I cruise at. I'd rather have the towing power, and quicker acceleration from the 3.92. Same reason why I picked one that has air suspension, rambox, nav, parking sensors, ect.. I use them everyday. All the stuff mine has further increase the usefulness of my truck for me.

For you, or others, that may not be the case. Higher speed highways apply to many, hauling wide objects in the bed, lifting the truck, maybe the price tag is the deciding factor.. All those examples may negate the setup my truck has for others.

For what you are doing with your truck, a 3.21 would be my choice.

I have a 3.21/8 speed now. (3.92/5 speed before)

I left the "Lower gearing gets better mpg in the city" camp when the 8 speed arrived.

Granted, I do take off 'easy' but Jeez, I'm usually in 3rd by the time I get through a typical urban intersection. Lower gearing wouldn't ~help~ me any.

But, in all sincerity, don't let 0.71 difference prevent you from focusing on the rest of the deal. In your case, with your usage, it's certainly not worth a lot of worry.

TAKE MY EYES BUT DON'T TAKE MY 3.92's!!!!

 

[SlowRoller]

TAKE MY EYES BUT DON'T TAKE MY 3.92's!!!!

LMAO!

I guess that's one more vote for the 3.92!

 

[Hemi450hp]

Adding a limited slip unit to the rear is a lot easier and cheaper than doing a 4wd gear swap, so I would get the truck with 3.92's and just add the LSD after you buy the truck. 3.92's with an 8 speed and an open diff is just going to smoke down 1 tire every time you go WOT from a stop. You will appreciate having that LSD with that gearing.

It is a sales ploy the 0% or pay 4k more crap. They need that truck to move asap. Stick to the numbers you are comfortable with. Keep in mind there is going to be like 2k more in taxes and fees on top of the purchase price.

I got what I felt was a great deal on the last 2015 RCSB hemi. The 3.21 gears with LSD. Would have preferred the 3.92 of course for the quickness. But I don't haul things regularly and spend most of my time on the highway. I could buy a set of gears and put them in relatively cheaply but it voids the warranty on the rear end. The dealer is happy to do it on a RWD for $1800 and retain the warranty. Im not sure if Im okay with that just yet.
