Transfer case upgrade

Is it possible to regear a stock transfer case with the 4:1 the rubicons have.
I have the SYE kit on an 03 tj with 4.56 gears and 35's but would like a lower 4 low.

I believe there's an option for 4 to 1 np231 on grimmjeeper gear ratio calculator, so it must have been done before.

Is this enough gear reduction over stock to be worth the price. Looks like something I have to have

You could probably find a Rubi xfer case either cheaper or that price.

yup, but there is additional accessory cost for the conversion...harness/wiring @ ~$50, speedo calibration @ ~$100, 1310 front yoke @ $75 , new rear driveshaft @ ~$300, Novak cable shifter @ $170...with the going rate for used 241's around $1200 right now, you'd have close to $2000 into it by the time you're done. .

If it just LOOKS LIKE SOMETHING YOU NEED, you probably don't...

Rokmen TT, Rokmen control arms, Novak NV241 cable shifter, JKS 1.25" BL + 1" MML.

Anybody can take advice if it doesn't interfere with their plan.

Is the 241 an exact fit, no mods necessary?

I misread your post. The kit is the better way to go not the rubi xfer case.

Very happy with my Tera Low, The rubi case was not an option with my 4cyl, but I can't imagine an easier way to get 4.1. Literally a couple hour job and done! No other mods necessary. I'm easy on mine, I like to rock crawl (literally). If you use it like it was intended I think they'll last a long time. If you beat the piss out of it, (high rpm's) gonna have problems sooner than later.

You are absolutely correct on that one and how many folks have ya heard whinning about their rubi case going to **** in a hand basket? Except for the ones that didn't take care of their angry sparrows.

Which transmission does your 03 have? 4.56 and 35s sound more like a manual setup, but if it is an auto your best option for additional gear reduction is a Rubicrawler.
