Transfer case, '95 vs '97?

[truckyard1]

In the course of my big body-off project I'm busy swapping the engine and trans from my '95 over to the '97 frame. The Transfer case from the '95 has a long flange that looks like the driveshaft just slides into, while the '97 has a bolt on flange. Is there a strength/utility difference between these 2? They both bolt up the same to the trans so that's not a problem.

no both are 13-56 T cases i don't remember when they switched to NP cases though

No they are not the same a '95 is a 1356 a '97 is a 4407, your rear DS from a '95 will not work on a 4407. IMO the 4407 is stronger.

Cool some info i never knew. Were all 97s 4407 cases? Mine I thought had the 1356 in it

All '96-97's that I have seen use the BW4407

thats correct my 96 had a 4407 too.

Awesome info! I'll just swap in the '97 DS as well

The only thing to watch out for on those 4407s is the front outputs. They are the only weak link and more than a few cases in the yards out there are missing the front yokes as a result. I had to buy a whole case just for the front yoke for my uncle when he broke his last winter.

So is the front yoke from the 1356 swap-in-able into the 4407? That'd be the best of both worlds, eh?

What do you mean about swapping in the '97 driveshaft? I thought the '97 was the patient receiving the transplant. Isn't the '97 driveshaft already there?

Well I had removed it to replace the center support bearing, plus the possibility of using the '95's TC
