An Engineer's Ultimate Guide To 3.21 VS 3.92 Axle Ratio

[theblet]

Yes….of course. My butt dyno shows at least 50 hp. Compensates for not having 3.92’s.

Well, I’ll get two then!

I haven’t been on this site for months. I come back and find this thread still going. Right on, I love petty, not only Tom and the Heartbreakers.

What kind of oil do you recommend for the 3.92? Is it different than for the 3.21's? I think I remember reading something about using boutique oil will help compensate for getting the wrong gearing.

I think the 3.21 grocery getter truck requires lavender and lilac oil doesn't it?

What's worse, is you're debating this at 3:17AM...LOL

But only if it is sustainable, responsibly harvested, organic lilac. The lavender should be pollinated by biodiverse bees!

Two butt dynos, or two sets of gears?

Got my 2022 with 3.21.

On purpose?

4:17 eastern time. I got up a little late. I promise I will be quicker to the draw next time!

Yes. Drove the same trucks with the 3.21 and 3.92. Chose the 3.21 because I do not tow more than 4000 pounds.

My new Ram is also 325 pounds lighter than my old Ford F150, with 35 more hp and 8 speeds versus 6. It's a lot faster and gets better gas mileage than my Ford with the 5.0 V8.

I love my new Ram's motor and transmission and gearing.

Last, I hope you find your dream truck with the brown/beige interior you prefer.

4.17? That’s the gears my truck has. Guess my build sheet is wrong.

Hey, at least you picked the right truck this time.

I'll probably be in a 3500 when they redesign them. Hopefully they put something like I wanted together.

It's the time warp thing from the 3.92 speed. It's hard to align the curve. There's a wormhole effect.

Good thing your truck only weighs like 4k lbs.

Guess you'll have to change out the diff after towing that Z06.

Nah, I'll just throw the truck away
