kluneV vs. Atlas vs. Tera-low 4to1

I am getting ready to build up a yj so give me your opinions on obtaining a low crawl ratio from the transfer case (np231). If there is any better ones than this let me know.

before you get flamed too much why don't you go ask this question here! hell, you didn't even spell Klune right. seriousally, do your homework before you ask an open ended question like this...:idea:

You are really comparing apples to oranges. If you can afford the Atlas, then get it. It doesn't even compare to modifying a 231.

The Kluve V adds length to your drivetrain so it's not really an option for you unless you are doing some lengthening to your wheel base.

Hey! They make a KloneV now!! I wonder how the klone compares to the real KluneV!! :D

But seriously if your gonna dump the $$ I think you should search, and browse through posts and learn what each thing is, and what it does, and if you really need it or not...

You know the greater the crawl ratio (slower you go) the easier it is to break shafts from torque,. so you HAVE TO upgrade your d35/d30 too... $$$

Search!! :rolleyes:

in my opinion the klune is nice because its a little cheaper then an atlas - you have a low enough gear- its real tough- and you can still keep 2.72 low range in your exsiting case- but on the other arguement- atlas is shorter then the klune addaption- cannot retain your 2.72 low range - Jess/ klune aprox. pricing 1734.00 -atlas 3.8 starting at 2200 aprox. depeeending on addapters and such and upgraded splines and yokes and such-

Well there are some fella's out there making "Klone-V" crawler boxes out of NP231 planetary sets.......but the newbie still gets flamed :flipoff2:

I my opinion the additional ratios available with the Klune setup make it a killer combination if you have the drivetrain real estate to make it work.

What I'd like to see is a three-speed planetary reduction box with a 1:1, a 1.34:1, and a 0.75:1 overdrive, couple that with off-the-shelf (read: non-Atlast I'm broke) t-case stock gearing to get optional low-ranges like 2.04:1 OD-Lo, 2.72:1 stock Lo, and 3.64:1 Lo-Lo, coupled with a granny gear truck 4-speed (like a super-short SM420) and you've got lots of gearing options for low crawl and highway driving.

sorry about the miss-spelling of the klune V, I even looked over my post carefully so I didnt get ripped. kinda fawked that one up. Any way thanks for the feed-back. I was trying to compare price and functionability. And yea everybody would love to have an Atlas but the money I have limits my projects :( .

The rest of the 90 wrangler has:
D44 rear w/detroit
D30 front open (soon to be replaced)
2.5L
5.13 w/36 tsl's
soa on 4"

If you have a 2.5liter, the atlas could be overkill. Depends on how easy you are on the gas.

a 4:1 kit in the 231 with 5.13s gives you a prettyo good ratio.

I have the 5.13's for the rear and I found a website that says they make 5.13's for a 30 I am just waiting untill next paycheck to order, there is a possibility that 5.13 is only avail. for standard rotation.

-also why is 9.5inch on 36's scary?

5.13 in a d30 is scary 4.88 in a d30 is scarry.. 36" on a d30 is scary..

10" of lift with 36 and stock wheelbase / width is scary..

Im gonna be running Full Width / SOA / 1.5" Springs with 38.5" tires... the lower the COG the better stability...

you can save a hell of a lot and just go this route and get lower gearing than the atlas.

435-203-d300

sorry about the pic but the flash likes to reflect the machine bit pattern (there are no little circles)



the adapters will cost you about 600 bucks or so

i'm running almost the same thing. 2.5(304 in the shop!!) 4" soa but 60 and a 44. i've got the 4to1. love it. i also looked at the klune, and with that motor you've got all the room in the world. slide the motor forward as much as you need. cut down that monsterous fan housing and gain the nose wieght for the climbing. i would think you can run the same drivelines if you do it right.:beer:just a thought from the other side of the river! calaveras baby

well If i go with a wag length front d44 how much wider will I be than wide-track because maybe I can throw some spacers on the rear.

also the picture you show with the adapter- what is a 435, I do have some d300's avail., and do you mean 231 not 203.

A "435" in an NP435, four speed tranny out of Ford trucks, Broncos, Dodge trucks. Stout unit with a granny first gear (6:1).

A 203 refers to an NP 203 tranfer case. The reduction section from these t-cases is commonly used between the tranny and t-case as a reduction box, as in the Klune V. It requires a special adapater to mate the 203 case section to the t-case.

If it were me, I would get rid of the 231 in a heartbeat. Even with a 2.5L, hard wheeling will kill it. A Klune V will speed that process up. The tera kits are really not worth the cost, when you add in the SYE, 2WD shifter, wider chain, and you are still left with a really weak case, and weak front output.
A D300 is a step up, but still not quite cost effective.

ATLAS II 4.3 W/HD output is the way to go. The 300 is a good gear driven case if you don't run big tires. By the time you put a tera low kit and a HD output you would be most of the way to an Atlas money wise.
