Front and rear gears

[RCMUSTANG]

Based on these charts I found on Spicers website I'm wondering if up l upgrading to 4.27 or 4.46 with these units is possible. These are listed for the Bronco and there's no other details as to what the parts include. Is it a complete diff or just a set of gears? It lists a master rebuild kit number under each unit. I've only found one place that even carries 4.27 M190 front unit but with no description at jegs https://www.jegs.com/i/Dana-Spicer/094/10130627/10002/-1
I would love to upgrade to 4.27's. It definitely lugs since I moved to 33's. Anyone with any insight on these?

First off unless there is a problem with your transmission (and I mean major problem) there is no way you are lugging.

Second, unless you are going bigger like to a 35 you have no need for a re gear. I ran 33's on my 2019 and did just fine.

What could be your problem is the tire choice you have. For example I went with the Firestone Destination XT Wich weighs in at 51 lbs a piece. Compare that to a KO2 in the same size and load range(load E to be exact) and the tire is 58 lbs a piece. Go to a mud terrain and you can forget it.

Put simple the tire you have may just be to heavy. If you haven't done so already just get it tuned. Also tow mode seems to help a bit for daily driving.

EDIT: was going through your build page(some neat stuff to say the least) and saw you already have it tuned. With that said if you are only running 87 I suggest going to a higher octane fuel like 91. It will make a difference on driveability and most likely a difference MPG as well as long as you are trying to drive for MPG.

Yes, it's luggy. My tires are now lighter than the LT's I replaced. The rpms are too low from where they were from stock for 55-65 mph on the freeway. That requires more throttle than before and getting into boost more than before and/ or having it downshift. And I have both 87 and 91 tunes available. Regardless of my or your opinion whether it's luggy or not, the point on the post is does anyone know about these part numbers so we can swap gears or not. I'm sure there are those who want to swap gears for whatever reasons they have. Too much of my driving in Los Angeles keeps me at 1,300-1,600 rpm in 10th. It lacks power without getting into boost. Bumping to 4.27's puts me back at the speed/ rpm range when it was stock.

So, comparing the Bronco and Ranger axles it looks like it may be possible if you can swap these 2 shafts inner and outer if the Ranger housing won't accommodate just the gears and welded diff. Hopefully someone with more knowledge on these axles and chime in and verify. They look very similar.

Is your truck tuned?

With my heavy E-rated 33"s and my Unleashed tune I have no issues. I cruise right at the tip of boost around 1900-2000 rpms. At 60 I'm cruising at 2k in 8th.

Much cheaper solution. You have 10 gears in a tunable transmission. Use that.

It's tuned and no I'm not going to go through the trouble of manually shifting on the freeway constantly. I'm not looking for your solution. I'm looking into swapping gears regardless of my reasons or your manually shifting solution.

I'd think Dana Spicer has gearsets for these. The rear advantek 44 is a very common axle at least, the front 35 is probably used in a lot of vehicles also. I'm guessing you can change gear ratio in Forscan?

These are the things I'm trying to verify based on the charts I posted. There isn't much detail or even pricing anywhere. While it may seem like they're used commonly there can be minor differences that won't make them compatible. There are virtually no listings anywhere for Rangers. I haven't plugged into forscan in a while to look at gear correction.

I don't manually shift. Why would you ASSume that's what I meant.

I'm sorry that I offered you a solution to the problem you started a thread about. A solution which is KNOWN to work. And costs orders of magnitude less than the as yet unproven Bronco gearset swap.

If you are just dead set on changing final drive ratios, why write multiple paragraphs about why.

Also, if you are tuned and your truck still lugs like that you need a better tune.

so I dont have the answer but im interested to find out. I *think* that the beefier gears will fit the ranger. my truck runs fine down the highway but better gears would be be sweet as we could get a better crawl speed. the 190 is a D35 and 220 is a D44 likely some of the most popular diffs built id bet some one makes a setup for them. Best answer would likely come from Dana Spicer direct. Some place they have a Ranger page and Bronco page with parts that fit listed. Thats where I found the better u joints. If I find it again I will post it in this thread.

I'm tuned with Torrie. So, in order for me to be at those rpms I would have to manually shift because it does what an automatic transmission does, it upshifts. This post is trying to verify if a gear swap with these part numbers is possible. A gear swap may not be what you want to do but others might. Again, not asking for alternate solutions. And writing multiple paragraphs? I'm responding to this offering alternate solutions.

I've reached out to multiple places and a couple have no idea so far. I've searched online pretty extensively at this point and there are virtually no answers or known gears that are confirmed to fit. Bronco guys have ford backing them in this so they have choices.

you may have already tried in this spot. if not worth a look.

 

[9zero1790]

i ran into the same. spicer and dana have fancy pages full of stuff for bronco and jeep but the ranger has very little despite sharing many of the same parts.

Are you using @TORQUERULES shift strategy?

Doubtful, because again, I cruise at 2k rpms at 60mph in 8th in D on Erated 33"s.

Since youre already tuned with Torrie you should just tell him where you want it to be and he'll do it.

Change gearing if you want. I'm simply telling you an easy way to accomplish the same goal.


I hear decaf is good.
