qtrac vs the world (kinda)

alright just for the sake of argument since there are sooooo many d300 vs. 205 and other threads. how does a bw1339 converted to part time stack up against a np208 or a np231 or any other aluminum chain driven case. just curious, thanks

i have a part time conversion kit installed in mine. you'll need manual locking hubs. the only thing that i do not like is the 2wd/4wd is vacuum actuated. there is a guy in norway that converted it to a manual lever action. here is the link. i'm not too keen on the high/low lever being under the seat either. other than that it held up to my amc360 with my right foot mashing the gas to the floor. sent power to front and rear axles throwing mud everywhere. i'd rather have a twin stick shifter and a lower low range.

i loved my q/t with 36's and some nice mud flinging no problem. with that being said the only reason i went to a d300 is the twin stick ability and the dominant rear wheel drive. i mean short of the d300 blowing into little pieces, even if it split in half the drive to the rear wheels would not be affected, since i do alot of wheeling on my own in the woods, i have to be able to trust that i can get home...i dropped a front driveshaft and would never have made it home because it wouldnt go into e-drive. with that being said i could have simply part time kit'd it and been done with it. but since i had to rebuild a th400, i swapped tailshafts for the d300. That is the only reason i went to d300, i may even put a q/t behind a sm465 and run it in my daihatsu rocky

We have been broke down on the side of the road with a QT. Yes, it is true. But, from what I understand about the buggar, I took a couple feet of nylon rope and fashioned a wad with it to hold the shift fork in place for Edrive. I also crafted a wedge out of a piece of wood once at the Ouray KOA in 04, took the shifter cover off and squeezed it in there to hold it in 4WD for a converted QT. ColeTrickle's Honcho is still running that way.

With manual hubs, you can remove drive to the front wheels too if you need to also.

As for the part time kit, it makes the bottom end of the QT stronger. Not sure how to compare it to the 208 even though I drive one most the time but would say they are probably fairly even matched.

The weakest part of the QT is that the chain drives BOTH outputs, instead of just the front. So the chain wears out a lot faster, and wont hold up like a moremodern case will.

Agreed. They definitely go through chains faster than a 208 would.

How much in comon is the BW1339 to the 1350? I know that the 205 dosent stand up behind cummins. But the 1350 does.

the 205 holds up to the cummins it was used from 89-93 is aside from the constant seep and leak it holds up really well just sometimes a bearing might sieze and then things break. BW1350 behind a cummins?

youre kidding,right? if you know of a situation like this,it was a fluke for the 205 to blow up and a stroke of luck for the 1350 to not.

no way id put the torque of even a 4bt thru a QT if i was going to wheel it,or tow with it.

the QT was ahead of its time in full time 4wd with the limited slip center diff and the lightweight aluminum housing.compare it to the other full time case of that era-the 203. with the 203 you could easily get 1 wheel peel on only 1 axle on wet roads in fulltime 4x,and it weighed as much as the rest of your drivetrain

a QT in good shape,with a good chain and properly maintaned is a very reliable case for inclimate weather driving,maybe light towing and moderate wheelin with reasonable tire sizes.

there are a couple things i dont like about them when it comes to abuse(abuse being heavy wheelin with 35+ sized tires or towing). the first stuka allready said-the chain drives both outputs.if it breaks you have no wheel drive. and when it breaks,it usually does so catastrophicly,leaving the rest of the case in small rubble chunks. a modern "straight thru" case like the 208 only uses the chain in 4wd,so it hardly wears,and only needs to be a fourth of the size of the big QT chain. in the unlikely event the chain breaks in a 208,youll likely limp it off the trail,and the case may be rebuildable.

another thing is that the spline engagement in E drive is very small,and thus,a converted to part time case has little spline engagement holding the front driveshaft locked in. its not unusual for a part time QT to shear these splines. true, the diff is replaced with a big solid chunk of non-breakable metal,but the spline engagement for 4wd is a big issue.

last and not least, last time i checked(but its been awhile,so i could be wrong) only overdrive part time kits are still available new,so only chance of finding a direct drive kit is to find a very old used one.

this cuts your axle ratio back when in high range,and also takes away some of the 2.61 low range,so youll have to compensate with lower axle gears.

in summary-yes the QT is fairly durable case for what it is,and a great option for those needing full time 4x.

but is it an apples to apples comparison to a 205 or d300? not IMO,for whatever its worth

Since when has dodge put a BW t-case in any full size truck?


A 205 is a VERY strong case, yes its big and heavy, but it would easily live behind a cummins.

Don't know how the 208 stacks against any other t- cases ( only had one ), but from my own experiance of thrashing levy roads that are soaked with mud and at a near 40 degree incline, and going into cane fields un-invited, i'd say the 208 can easily hold its own!

I think the full time non-overdrive kits are still out there. I purchased one on ebay that the seller posted as an overdrive but it was not. I think the instructions were for the part time kit so he assumed it was. either research the part number or have them count the splines on the replacement center section. another clue to look for is the overdrive kit always came with a new chain. non-overdrive can come without a chain and without hubs.
