Gearing option w/ OEM lockers

[blobmaster]

So recently picked up a ‘95 x3 locked and have been looking into upgrades/mods and of course lift & tires are the first thing. With tires it seems like it would help to re-gear when you get into the 35” range, but with the factory lockers does this affect the ability to do that? Seems like the factory lockers work different than most and could change my options for gearing. Thanks in advance, still learning a lot haha

It’s fine. Just call nitro or Yukon and get gears

Sweet! Yeah I’ve seen a few people mention that there isn’t different gears for ones with OEM lockers, but it was on ye old YouTube which isn’t nearly the around as here lol

The gears are the same, locked or not

Thanks! I know I ask a lot of simple questions but don't know a better way to learn haha

Some carriers have a split. Meaning due to ring gear and pinion gear size the carrier will be for a set range of gears.

For the gears you'll want to run, the lockers will accept those gears.

Simple questions are good! They require simple answers

Lots of us run 4.88s over 37" tires on factory 3x locked rigs which results in a final drive ratio virtually the same as stock/original.

What kind lift do you need for that tire size? 37” are probably overkill for intended use haha, but I think I wanna go up for 315

Lifts don’t help you fit tires. I always recommend a 2” lift due to the short list of required supporting parts.

If you rig already have lockers and not planning to run more than 35s, i would just regear the transfer with UD gear set. It's cheaper and pretty
much put you back to stock gear with 35s.

Sweet, I’ll look into that. Any disadvantages to just doing the TC rather than the diffs?

 

[Road Apple]

Transfer case gears are cheaper. Regearing the diffs is $2000 to $3000 depending on what part of the country you live. Regearing the t-case is about half that depending on how many sets you replace. Usually the t-case is removed and the work is done on the bench.

You can add a set of 25% low range reduction gears at the same time. They require grinding the case a small amount to clearance them. A noticeable difference crawling through the rocks.

Check out this thread for more on the discussion including good input from Otramm.

TC gears vs diff ring/pinion for regear?

I'm planning on regearing my Cruiser this year. I can either regear by replacing both the high and low gears in the transfer case or do the more traditional method and replace the ring and pinion in each of the diffs. The TC gears is a 10% underdrive which from my calculations with 315's is...

To be clear OEM lockers require a defferent set of gears then none locked

Well, kinda. Lift allows for wheel travel. Upward travel

We usually do a 4" lift for 37s. I am on 4" and 1" spring spacers, custom sway bar drops, and 2.5" bump stop spacers. When I am totally crossed up in the rocks I get a wee bit of rub in the top of my reat fenderwells, but no damage, xjust shinny spots.

It’s a sticky subject filled with lots of caveats. But for simplicity I like saying that lifts don’t help you fit tires, bump stops do. With 35s, I rub the same amount with a 2” lift as I did with a 4” lift because full bump never changed.

But you’re totally right, more lift does equate to more uptravel so you can afford to add in bump stops and not cut into the body.

At the end of the day there’s no clear cut answer.
There’s just too many variables

Agreed. Lots of ways to skin a cat
