3.92

Hello fam, I have a 22 ecodiesel 1500 with factory tires/wheels (22's) and 3.21 gears. im wanting to put on 35's. Im not concerned with rubbing (have revel links coming in mail) but I am concerned with wear and tear to the transmission and possible major hit to mpg's. Ive seen quite a few people...

So I am changing the diff oil on my 1500 and I know I have the 3.92 with the amti-spin option. I don't know if I have the max tow package or not and I can't find anything outlining the difference but they do call for different oils. Can anyone help me here? "Max tow" package isn't on my window...

Due to putting on 35+k miles a year I'm thinking about swapping the hemi for the ecoD. Not much towing, lots of commute (usually 65 to 75 mph) and then driving on rough muddy jobsites (>10 mph). 1. If I swap to 295/60r20 or 35x11.5x20 tires am I going to hit myself for not getting 3.92 gearing...

I have a 2019 Ram 1500, 5.7L with 3.21 rear gears. I want to swap the gears to 3.92s. Does anyone know what other modifications would be required, if any? Computer reprogramming? Trans cooler? What exactly are the differences from factory other than the gears?

I recently bought a travel trailer with a overall length of 32'm 7500 dry weight and 833lb tongue weight. My question is because I just recently sold my truck 6 months ago and now need an new truck is what to get. my old truck was a 1500 big horn. Id love to get a new 1500 because I only tow a...

Hey all, I'm having an issue in which my 2019 Ram 1500 Crew Cab 4x2 Laramie 5.7L V8 with 8 speed auto with 3.92 rear axle ratio and am hoping you can help. Upon braking and downshifting and perhaps more when vehicle is "cold", transmission occasionally falls out of drive without user input. The...

I purchased a 2020 Ram 1500 about 6 months ago and want to do a gear swap. Ive searched high and low and cant seem to find any aftermarket ring and pinion sets for the swap. I have a 3.21 and looking for a 4.10. It is a 2wd so the front end isnt an issue here. Anybody know where I can find them...

I hope this post will help to end the debate with facts and not opinions, and become THE post people refer to those who are having a hard time deciding. You already know that 3.92 is better for towing, and 3.21 gets better fuel economy, so I will talk about what you might not know Bottom line...

Just got home from my first road trip in my new truck. (I’m very pleased with the results) Me, my wife, and our three cattle dogs. Phoenix AZ to Ouray Colorado in the San Juan Moutains. First photo is the outbound drive last Thursday. Including two mountain passes. Speeds ranged from 60-75...

Hey all, figured I've posted on enough threads now to comfortably make my own. Since I am at 1100+ miles now, beyond the recommended break-in, I felt it was safe to do a proper wide open throttle acceleration run. I couldn't find any 0-60 videos that were for-certain running a 3.92 axle ratio...
