Ok I'm considering a 4:1 transfer case upgrade so I can keep my street able gears in the xj but have the crawl ratios / lower gearing for

Who else has done the conversion?

Pro's and Cons?

The options I have found are the

Teraflex (there are some reliability questions for early versions)

Jeep Rubicon Rock Trac - used cost about the same as the teraflex and their will be a little loss of ground clearance

Atlas - cost is very high compared to the other two but....it the best you can go

 

Look at a flipped dana 300 t case swap,You can twin stick it and a lomax 4:1 gear set for it for 650 bucks.

 

More info please...a link.

That sounds like an option

 

http://www.pirate4x4.com/forum/jeep-...-tricks-3.html look at post 66,The dana 300 you want came from CJ-5 (1980-1983) CJ-7 (1980-1986) CJ-8 Scrambler (1981-1986) any other info you need is all over the pages of the forum.

Pro: Awesome, you pick your gear ratio, good for future builds and it's guaranteed. Oh, and you won't have to upgrade ever again. (:

Con: Expensive, but make sure you check out the total cost of working with and installing other units.

 

or do a 231/300 doubler, then you get wicked crawl ratio and three sticks

 

Do an upgraded output shaft and yoke if you decide to waste money on a 231/300.

 

Yeah screw all those options. If you're not gonna swing an atlas, just do the teraflex kit. It will at least hold decent resale value when you are ready to sell. Simple and effective

 

I have seen way to many 300's blow, sometimes it's just the outputs, but way to many times the wholes case cracks. I ran a 241OR for about 5 years, never a bit of issues, strong case, great gearing, I now run a STAK 3 speed (I was worried about it popping out, but so far so good) only reason I sold the 241OR was that I got the STAK at a steal. I would recommend Atlas 1st, then 241OR, not a fan of the teraflex 4:1 231 kit either.

 

Screw a teraflex unless you plan to crawl a light post at the mall. They burn up easy off road or anything above 2.3k rpms..

Used 241ors can be had for 7-1000. I paid $800 shipped w/ 1310 yokes installed. Way beefier than a 231

 

x2 on that cheapest best way to get 4:1... where the hell did you get one for that cheap?

 

I sold mine for $850, picked up, but it was to a good friend.

 

So options for us best to least

Best - Atlas
Np 241
Terra flex
300
231 with doubler?

 

I've wheeled with you, you just described your exact driving style

has the availability gone up on the 241OR? that's definitely a better case, but I've been scanning multiple "for sale" boards for years now and don't think I've seen one at all that I can remember.... definitely a better case, if you can find one.

eh more or less. I usually just keep an eye our for deals like this
http://www.pirate4x4.com/forum/engin...-tulsa-ok.html

that's how I got mine

 

those deals are rare. the availablity has definitely gone up people find them in junk yards all the time if you get lucky and find a rubicon most junk yards don't know the difference from a 242 and 241. ebay even sells refurbished ones. now 800 installed and shipped is unheard of yes. but 800-1000 is a good price for a used one comparing to the other options is the best deal imo.... theres even one for sale in our buy sell trade i would jump on if i had a grand to blow https://www.cherokeeforum.com/f72/np...o1-low-219995/
