Best Chain Driven Transfer Case?

Hi all,

After my most recent trip to the junk yard, I brought home a ZF5 and the attached BW1356.

So, now that I'm thinking things over for my build, I'm curious which transfer case is considered the best out of these three.
I have an NP-208, BW-1345, and a BW-1356 in my garage.

Pros and cons? Which should I go with? Which is the best chain driven TC?

Hey AB

Is the 1356 manual shift, I can't remember?

from my reading, the bw1356 can handle the most torque and abuse. They did put it behind diesels before the 4407 came around in 96. The oil pump is the weak link, and there are upgrades available.

I haven't heard a lot of great things about the 1345, and they didnt use it very long. The np208 is about the same strengthwise. Both would be fine I'm sure, but I would opt for the 1356, which happens to be the newest too.

Hey buddy,
The 1356 comes in both manual and electric shift. The one I have on hand is a manual shift, but has an embossed spot on the casing telling that it's where the electric motor would go.
However, I read that the electric shift has the fixed yolk tailshaft whereas the mechanical has the slip yolk. The one I have has the slip yolk, which obviously won't work with a slip joint driveshaft.
I might see if I can track down a BW1356 with a fixed yolk and combine the two. Then, sell the two NP208s and BW1346 I have to regain some.

I hadn't even heard of a BW4407 until just a few days ago.

The bw4407 is massive. My f350 has one. Dry, it weighs 115 lbs. It has a 6 pinion planetary vs the 4 of the 1356 and has a bit wider chain. It's also a flange mount for the driveshaft.

I've never had a problem with any 1356 I've had.

Correct, I would not use the slip shaft TC with the bronco driveshaft. Too many parts to get out of line.
