Hey guys. I'm planning on swapping my rear end gears from 3:55 to 4:10 but I need to know what size rear differential I have. I counted 10 bolts on the differential cover. Anybody know what size this is?

The option sticker on the glovebox lid should tell you the rear axle size. Anyway, 10 cover bolts is an 8-1/4, while the 12 bolt cover is on the 9-1/4 axles.

Details are helpful when asking questions online.
What year is your truck? What engine? 2wd or 4x4?
Dodge used 3 different rear differentials in the Dakota over the years, two of which have 10 bolts.
Besides the 8 1/4" mentioned above, some of the "N" body Dakotas (87-96) were available with a 7 1/4" rear diff which is also a 10 bolt cover.

That's right. If it's 2wd then rear is either 7.25 or 8.25 (optional). If it's 4wd then front is 7.25 and rear is 8.25. All w/ 10 cover bolts.

since it's newer truck then 7.25 is pretty much out of question. It must be 8.25/10 holes, oval shape.

it is not the 9.25. as he stated, it's a 10 bolt... 8.25
if you have a 9.25, you should have an octogon cover with 12 bolts.

if you want a DIY kind of thing, the best would be to get a Powertrax unit. They are pretty easy to do and dont require you to "setup" any gears.
