Here you go... Tiger.

 

wow.... someones a little light in the loafers

 

Sassy! Looks like Siegfried and Roy are designing t-cases now that they're out of show biz.

 

i always knew those things needed a wide load sign and backup beeper .

 

I was planning on trying to find a 271 for my '01 SD and replace the 273 and ESOF (electronic hit or miss shift to 4x4 on the fly) so I have a manual transfer case. Exterior dimensions and shaft size/spline are the same methinks. Then I can swap out the unit-hub knuckle junk with a Dynatrac fixed spindle system....................


OH DEAR GOD...MAKE THE MODIFICATION BUG STOP!!!! I can't afford another buildup!!!

Since I have no experience with them, I can't say that newer is/is not better. What I can say though, and with a great deal of certainty, is that I don't like chain-drives and I don't like aluminum cases. I don't mind heavy and ugly - face it, an extra 100 lbs doesn't matter in a 6000 lb truck. I have never seen anyone completely gut a 205, and that's the kind of durability I demand. So until I see someone flog the new stuff to hell and back for years on end without failure, I'll stick with the 205. However, the lower low gear in the 271 is attractive.

 

What I'd wonder about the 271 is if the chain will start stretching under high torque and abuse. But with the rating on it I don't imagine that would be a problem. Sure, gear driven is the way to go but the drop boxes in monster trucks are all chain driven, very similar Skipped Link's custom made drop box, and they're handling 1500-2000 horsepower.

 

but still no twinsticks!!!!!

 

Now that i think about it, petersons built up a superduty for t he utimate adventure a few years back , 46" mich's and a bunch of other mods, then managed to twist the 10.5 axle tube at th ehousing, cook the tranny, gernade the front diff i believe, and they never did have to touch that tc in it.

 

I figured up the difference between gearing of the 205 and my BW1345- 205 is 1.98 low range I believe and the 1345 is 2.74 low range. If a person had a truck with 3.50 axles and switched from the 205 to the 1345, it would be the same as going to 4.88 gears- in low range anyway. To me the extra gearing and the convienience of being able to lift the T-case in and out with my scrawny spaghetti arms.( even though I really doubt I will ever break it!!) Far outweigh the sorry low range, heavy weight, and supposed indestructability of the 205. And besides, do you really need a twinstick setup, or do you just think you do because all the "cool" kids have them?? I have done lots of wheeling (18 years) and have never been in a situation where I would have benefitted from a twin stick setup and I bet most of you are the same if you were really honest with yourselves.

 

Yes, I've been in quite a few situations where it was a major benefit and I haven't even done that much wheeling since I twinsticked my truck as it's been in the driveway in pieces for 9 months. I suppose it may not be near as important in a really short wheelbased truck but in my 20 foot long pig I've had situations where it's essential to be able to manuever around obsticals without plowing into them.

 

actually i have used it a few times. with the length of my truck the twinstick was a HUGE benefit b/c i could set the parking brake and turn on a dime! now some trucks with a shorter wheelbase i wouldn't think would benefit as much. but i am about to find out first hand

-cutts-

 

My question would be, how do you know you dont need something, if you havent had it?

 

I just remembered, wyld has 4 wheel steer. That would explain why he wouldn't need the twin stick as bad.

 

Wyld, you bring up some excellent points, to which I offer the following:

1. I run mud exclusively, no trails. I don't think twin sticks will benefit me, so I don't have them and don't want them.

2. While low range in the 1345 is lower and will yield 4.88 equivalent in your truck, I run 4.88s because I have big tires and still want a useful 2-speed tcase.

3. As to the "supposed" indestructability of 205s, I have flogged mine unmercifully for about 10 years with no problems; no bad seals, no broken gears, no damaged yokes or outputs. In the last year I've gutted both diffs and completely grenaded 1st and 2nd gears in a T-18. When I'm home again I'll take a pic of my bro-in-laws 208 with a busted gear. He runs a very similar set up to mine.

4. "sorry low range" - while not as low as other cases, this is subjective. Get the diff gearing right and you're fine in mud. If you're doing serious rocks, even a 1345 isn't low enough. Most guys run 3- and 4-to-1.

5. Additionally, the 1345 has an internal oil pump (mostly plastic). I don't like the idea of depending on one of these to keep me going. The 205 and 208s depend on gears/chain to sling the oil

6. In the original Green Submarine (208), I stretched chains on 3 or 4 occasions to the point I didn't have 4wd. At that point, gearing doesn't mean squat. I swapped over to a 205, no more problems

6. Like most everything else on a rig, build it for what you personally want. As I mentioned above, I have no experience with the new cases, and probably won't in the near future. The 205 works for me without fail, and fits my prejudices; so that's what I use. I don't begrudge others because they choose differently, maybe they don't have the same parameters of use I do. I'm just offering an opinion based on my experiences and those of people I wheel with.
