ok.whats rong with the 205?its a proven unit,stong,easy to get parts for,you can gear them way down.so my other question to you is why a doubler.the best doubler setup in my opinion is two well built dana 300s.I rock crawl with guys running all sorts of doubler kit.they'er all different and you don't need one for mudding.I have 4.10s and I don't remember what I put in the t-case but I'll find out for you.this is a ford f250.I can pull at loaded stock trailer and keep up with the new rams,strokers,and duramaxes.I can also smash through a 4foot deep mud hole with 35s and never lose traction.yes I do get stuck.every boddy dose but is what I'm saying is for mud and road use just go with a good well built 205.it wont breake.if you breake a good 205 you wheel a lot harder than I do.

i broke a 208 in half and that was with my measly 39s, 460, and heavy foot! i woudlnt use that case b/c if you really do wheel with 53" tires and 25" of lift it wont last even in front of the 205!
for someone with 53" tractor tires and rockies and 25" of lift you sure seem tight on the wallet when looking at shellin for a doubler kit!
hey, if someone wants 2 feet of lift on their truck so be it, i've got a winch on the front of the bronco that can get the tires pointed back down

I'd say upgrade to the 205 case and call it good. I'd also invest in a good roll cage for your cab with that much lift and tractor tires.........
Where are the pictures of this thing?
Maybe you could post it on ebay for sale and we could start a thread about it here.....

there was a guy down in tx that run boggs has same tires and axles you got.what he did to overcome power and gearing was to install 2 460's one under the hood and the other in the bed.the one under the hood run threw a c-6 205 then that drive shaft(rearonly)went to a payloader case,then the rear engine was hooked to a c-6 from a car and that d shaft run to a divorce 205. that was mounted under the rear bumber and what used to be the front shaft on that case now run into the rear input on the payloader case.whats kinda cool about the whole thing was this truck was tall enuff for me to walk under it and the payloader t case put his d-shafts at a pretty good angle.if anyones been to the drags and bogs in nacadoches tx theyve seen it

im thinkin yall may be right i probably dont need both t-cases, with the 6.72 gears, i was thinking of going to a np200 as well there a little stronger than the 205. does anyone know which has a lower gear ratio
is funny somone made the roll cage comment, i just bought the steel the other day for it.
thats sounds like one hell of a rig wizzard351
thanks for every ones input.

So when are you post some pics of this monster. The other option for Tcase doubling is a Klune-V- provides 2-4 time gear reduction. Just a thought.

When I priced one for my Bronco I believe the unit was about 1800 Installed with new shafts etc. looking at close to 3k. from what I have read these things are bomb proof.
Search it there are some great links available.

Yeah, I think you would be better off using the 205 alone with a 3:1 kit. Those 6.72:1 "Rockies" and super low gears, dont make a bunch of sense for big mud. Wheel speed is the key here, and making the tire spin slower will only mean that the engine is at wot sooner with little to no tire speed. Even tractors get stuck, where a higher horsepower vehicle that can clean the tires (by spinning the mud off) can make it.
I am also wondering how one would get the front driveshaft to clear the front case by using two of them the way you are suggesting? Although, with some three miles of lift, maybe the front shaft will not move enough for that to be a problem. Even though the "Rockies" have the drive flanges so high.

when you mount the divorced case, mount it straight down so it clears and helps the driveline angle, but im prob just going to run a 205 and ditch the 208, because i well know about wheel speed to get through mud.

if you know all about wheel speed, why is running that steep of a gearing even considdered? From what I know, a good target for mud drags is a 90mph wheel speed to be competitive. Nothing to get that with doublers and rockies.
