400 trans, 205 & 203 range box. opinions please
Ok, I have read a lot of info about the 205,203,400 doubler setup. I would like opinions from those who use this setup.
Is $700 worth adding the 203 range box to 400/205 in a trail truck. How does this combo perform compared to a stock 700r4 and 241 c transfer case. Does fuel mileage decrease and is there power loss from running the heavyer parts.
Does the weight affect the frame over time? Is the shifting a pain in the ass and does maintance requirement go up or down compared to stock?
And lastly would you still use this setup or have done something different? Such as just using the 400 and 205 or even a lomax kit?

depends on what you mean by trail truck. if you're going to need a crawl ratio then there is no substitute.
Why not run it with the 241? The low range is better than a 205 and as long as you protect it from hitting the rocks it will hold up. $700 is cheap, $525 is even cheaper (jed's machine). Don't forget that you'll have to modify you're driveshafts and make a new trans mount...

The "extra weight" will not affect the frame: the 203 box is like 50lbs or something.
Doubling to a 241 would be pretty sweet... I'm going to think abou that one. 2.72:1 vs 1.96:1 in the 205.... so you'd have a better low to start with and even lower Low-Low. Hmmmm

If you want ultimate gearing, put in a 4:1 klune between the 700r4 and 241.
That will give you 3 low range ratios, 2.72, 4.0, and 10.88!
That will make your crawl ratios, 44.63, 65.64, and 178.53!

I did see on here were a guy was able to modify the 205 rails and shift it from behind. Just a thought.
