Spicer Dana 3.91 Differential gears

[FamilyCircus]

Ok, Ive decided to go with software and a new TCM for my 2000 Amtran with the MD3060 to get the 6th gear enabled. If you have a 643 or 545 or one of the non over drive transmission you might be interested in these gears.

This is a brand new set of World America ring and pinion for a Spicer/Dana N175, N190, N210, N320, N400.

The part number is 1665359C91

This will require a bolt kit to reattach the ring gear to the differential carrier and a bearing kit or 3 bearings for the installation of the pinion gear.

This is about 100lbs and can be expensive to ship but I am more than willing to box it up and ship it if you cant come by and pick it up.

Feel free to call or text me at 801-897-6560

Im asking $300 for the set plus shipping or just come to Utah and pick it up.

Thank You

Heck of a good setup for someone needing to upgrade to highway gears.
If mine wasn't already at 3.42 I'd be all over that deal!

Well just wanted to let everyone know I still have this gear set for sale, make me an offer.

Is this something easily installed at home, or does it require specialized tools, knowledge, experience, and measuring? Will it fit in a carrier that I'd be removing a 5.38 gearset from?

Thank you for the info request.

This could be installed at home but I would recommend taking it to a gear shop with your carrier and having them install it. I would do it my self but Im a bit crazy, so Ive been told.

This will only fit the Spicer/Dana N series differential carriers, it might fit others but I cant confirm that.

We have a gear shop here in Utah that would charge 250 to swap the gears in my carrier if I take them to him.

If you have any more questions feel free to ask.

brad, I missed this.. you have to look up your axle.. but Most axles have a carrier break at 4.10, meaning you need a different carrier for 4.10 and lower vs higher.. there may also be another carrier break up higher.. the reasoning is that numerically Higher ratios the Pinion gear is smaller. so the position of the ring gear changes.. differences in ratios are partially compensated for by the thickness of the ring gear and differences in the number of teeth.. but at some point the position of the gear needs to be different...


on most of the spicer / dana axles that break seems to be anything 4.10 and lower and then anything above that (up to another point after the 5's).. its published for each axle type.

Would you still happen to have these? I’m very interested for my N190 with an original 4.78:1 rear gearset. I’m in Colorado. I know it’s been a long time...
