Timeline on better gearing for bigger tires?

[Fordmandan87]

Is there anything in the works for regearing our unique differentials? I want to put bigger tires on but I also want my transmission to live after I do so.

There should have a best possible solution in the very near future. Until then, we already have vastly superior gearing to the competition. You shouldn't have any problems going up to 33 or 34 gearing wise.

I've had way too many issues with automatics to really trust them but then again they were all used/abused units that had over 100,000miles on them lol. In 10th the rpm gets almost too low to be of use in stock form. I figured a 4.10 gear would be enough to have a 33-34in tire and be similar in rpm to what stock was.

I'd think a tune (Livernois, 5 Star, etc) would make up for any performance lost by larger tires, and then some. Also, this transmission is used in full-size trucks so I wouldn't be worried about it holding up if your just looking to run 35s or something. Good luck!

You are correct - the gearing should be corrected for bigger tires or 10th may be unusable, depending on how big you go of course. The workaround would be to limit the trans to 9 speeds, but it's a workaround.

The trans, based on what we know, is the same unit in the F150, not sure if it's exactly as strong, they may have downsized some components so it's lighter, but it should be stout.

I'm with ya, I'd be comfortable going up to 32's with no re-gear, much more than that, I'd want to re-gear. I already don't like how much it lugs in 10th at times.

Your probably looking @ $1400 per end, installed.

Basically the same axles used in the JL Jeeps, so my guess is that there's already something out there, but nobody crazy enough to put it in the Ranger yet.

I believe the rear is a Dana M220 and the front is an M186.

Gears for them already exist at least in some form.

The front is 190mm. Just enough to be different

I've seen it reported many times the trans is the SAME one as used in the F150 - the only difference is the bell housing. The internals are identical.

I'm on 33s and haven't noticed any real performance difference. Truck did fine at my local ohv park in 4low going up some steep hills just idling. I'll likely regear if I decide to go to 35s, but don't see the need at this time.

These trucks need a regear after larger tires.
Even with a tune. 4.10 would be perfect for a 33. I have 32s and you can feel the difference on the freeway. My gas mileage has dropped about 2mpg as I’m having to use more throttle to maintain speed.

Anyone hear anything about this?

Originally, I was questioning 3:73 gearing, too. I can say, I'm running 33's now with no problem and no tune. However, I live in flat old Florida. We'll see how she does this Deer season in PA.
