There was a jeep on 52" michelins with a crazy bbc running an atlas. It had rockwells too. The caption said "So here is the proof that the Atlas *is* nearly bomb proof" or something along those lines.

My friend here has an Atlas in his Jeep TJ. It has a new 350 Chevy Ramjet motor - 700r4 - D60/14B - 4:56's - ARB/Detroit - 38" TSL's. He likes the skinny pedal and has no problems with his Atlas

A 205 is stonger than an atlas, unless they are using some sort of alloy metal for the gears which I doubt.

Yeah but a 205 isn't available in 3.8, 4.3, and 5.0 ratio's /forums/images/graemlins/thumb.gif

Yeah but you can't get an Atlas 5.0 at a junkyard for $20 /forums/images/graemlins/rotfl.gif /forums/images/graemlins/histerical.gif

An atlas has its place. It only offers 2 gears hi and super low. Have you ever tried to drive in sand, snow, mud, with only a 4:1 low. It sucks. Not enough wheelspin. I like the doubler for its options in gearing. I really like a klune in front of a 205 for even more options. I just like choices. And yes I do agree that a 205 is usually overkill but I like things that are bolt on a forget (like the 14FF and NP205)

The gearing options for a doubler aren't that great either. The reason is because both t-cases are geared identical ~2.0:1 /forums/images/graemlins/eek.gif If you ran a WMS 203 then you would have many gearing options. The other downside for me was the weight and length.
I solved the low/high range problem by installing a full manual valve body in my th400. I can start out in 1st, 2nd, or 3rd gear.
TH400/Doubler
High:
1st- 2.48x1.00= 2.48
2nd- 1.48x1.00= 1.48
3rd- 1.00x1.00= 1.00
low (205):
1st- 2.48x1.96= 4.86
2nd- 1.48x1.96= 2.90
3rd- 1.00x1.96= 1.96
low (203)
1st- 2.48x2.01= 4.98
2nd- 1.48x2.01= 2.97
3rd- 1.00x2.01= 2.01
super low 205/203:
1st- 2.48x3.94= 9.77
2nd- 1.48x3.94= 5.83
3rd- 1.00x3.94= 3.94
TH400/Atlas 4.3
High:
1st-2.48x1.00= 2.48
2nd-1.48x1.00= 1.48
3rd-1.00x1.00= 1.00
Super low (4.3:1)
1st- 2.48x4.30= 10.64
2nd- 1.48x4.30= 6.36
3rd- 1.00x4.30= 4.30
The choice to run the Atlas was easy for me. I don't see gearing choices much different than what Atlas user has if running a manual valve body. Sure they cost alot, but for those of us who 1) have the money, 2)are serious about cutting weight and wheeling better, the Atlas is a great choice. In all honesty I don't have much more in my Atlas than I would of had in a doubler if I bought all my parts at standard used/new prices.

I agree the doubler limits choices to a 1:1, ~2:1, and ~4:1, ratio. It does give more wheelspin (and overall options) than an atlas. As I mentioned above, I really wanted to do the klune V (2.72:1) in front of the 205 which is similar in gearing to the WMS 203 (3:1) set up, the price of the klune is a little steep seeing as I still had to buy a 205. Weight isn't an issue for me so I can't justify the atlas. For rocks only the atlas would work for me, but like I said I enjoy choices. It is just me, that and I am trying to keep a somewhat (although heavily rock biased) multipurpose DD/trail rig.
Nice numbers too. I really like it when somebody has some sort of stats to support an idea. Kinda brings a bit of tech into the tech forums. I see what you are saying with the same choices on a manual valve body set up. I guess it is a trade off as most things often are.

The Klune would be a nice addition in front of a 205. I myself want to run one in the future because the th400/atlas is too damn short /forums/images/graemlins/eek.gif the way I configured it /forums/images/graemlins/doah.gif If you are serious about the Klune, send me a PM and I can hook you up for much less than retail.
Klune's are light weight and strong to boot. They only add 6-8" of overall length to the drivetrain and you don't need any fancy adapters to use it. That does limit you if you ever sell it though.
