| Well Im at that point were things are starting to come together on the build. One thing that I am wondering is it worth having a 2.71 and a 4 low? My drive train is going to be very long so is it worth it? |

I had standard AX15 3.83:1 with a 4:1 and 4.88:1 gears. It was OK with a crawl ratio of 75:1 and 38" tires. I think 75:1 is more than enough if you are running an auto, but if I was running a stick its right on the edge of needing more. My new set up will be a stick with 179:1 and 44s. I think I'll be happy there.
Just my .02 |

My plan was to set up the gearing to use the 4:1 for the trails around here and the 2.71 for fire roads and any new Koh style racing around here. |

| You might want to do some research on the planataries your planning on using. I'm assuming your looking at a 231 or 241 doubler. I don't think they like to run at high rpm for long lengths of time. I know that they tera-low kits are easy to burn up if you run them to fast. I also had the planataries in a 231 in had in my Jeep come apart. I'm assuming from running around 360 too fast in low. Mine could have just been chance though. |

No thats one issue I have been thinking about. I have a D&D 241 doubler that will mate up to my 4l65. After researching it I might just do an atlas or stak behind the 4l65. Right now I can do the doubler and D300 I have but how long is that gonna last...
I would love a 3 speed stak or 4 speed atlas. |

Yeah that's a lot of HP to put in front of that combo and run it hard and fast. |

Staks suck. Only t case to have a "problem" thread on pirate for weeks on end. Ask Mudgod (George) what he thought of his 3 speed.
If ya want a broke t case run a 208. Actually they seem to be more reliable than a stak, lol.
With that said, I wouldnt go back to 1 t-case for anything. My setup: 465-203-205, with a lomax 3:1 in the 205 one day. NOTHING is more proven and durable. Period. My final is 134:1, and I would go lower, but not higher. Its about right where it is. If I need to spin the tires at all I put it in 1st or 2nd. Gas it in granny low and it just lurches, barely.
Keep in mind that you will be shifting it either way (auto or manual). You drive through the brakes at some point with an auto, and it reduces your auto to a finicky, lazy, hot running manual basically.
To answer your question: Yes, doubler or 4:1 or you WILL get left, but no stak, terra low, or D300.
Thats my $.02. _________________ 85 Diet K5 truggy on 43's, soon to have spray.

Hey Tomahawk there is a thread from early last year on here about the same thing. I dont have search ability on here maybe someone else can find it?
I dont know about the other brands but i love my set up. I went from a 2,62 to a 5.24 low BIG difference on the trail as a resulult in made my worthless 44 even more of a dud. I broke 4 shafts in basicly 5 hrs......... _________________ "Only two things are infinite, the universe and human stupidity, and I'm not sure about the former."

My Teralow has been in my Jeep for almost 10 years with no issues. I keep it under 1500 RPM when in low range and driving long distance. High range makes no difference. That said, I'm going to an Atlas now that the 60's and 42" tires are going on. Not because of the Teralow, but because I've seen the 231 cases fail (the outer aluminum shell) with real low gears and real big tires. _________________ 97 TJ, 06 Dodge CTD 4x4 |

My goal was the 2.71 for rock racing and 3.8 in atlas for crawling. And both when I needed to go really low. Now I am thinking of just the 3.8. Its solid and dependible. |

Could also do a 205 for the strength and rock racing.Then add a Klune in front of it for crawling. _________________

As long as you go with the "Goliath" Klune. IIRC the "David" version is not rated for fullsizes or a lot of HP. _________________ 85 Diet K5 truggy on 43's, soon to have spray.
