NP 208 transfer case brace

Hi everyone,
I'm new to the forum and to my M1008. They are both AWESOME!!!
The M1008 has what appears to be factory dual exhaust on the 6.2.

I've always been told that the brace (bar) running from the passenger side of an NP208 (attached by two large bolts running into the transfer case) to a bell housing bolt on the back of the engine is a MUST... this helps avoid cracking the transmission case under hard use due to torque reaction of the drivetrain.

My truck doesn't have the brace... the dual exhause seems to make package space for the brace difficult.

First, I want to confirm that these trucks came with dual exhaust from GM. Second, I want to check and see if the M1008 should have the transfer case brace installed from the factory (maybe someone took mine off and tossed it).

Thanks for any info available!

They came with dual exhaust and yes you have to have the brace.

The brace is a must. If you can't find one then make one. Very important piece.

That's what I thought. Thanks guys!

you really need them?? never had a cucv with one.. whats does it even do?

My m1008 had one on it when i bought it . All my k30 trucks have them . It helps to keep your transmission housing from cracking.

never saw one cucv with them thanks

Left it off when I went for a short ride after changing the flywheel to make sure everything ran right before putting the cover and braces back on, street driving. The cost was 1200, for a new 4x4 case and rebuild.

Mine does not have one, does any body have any pics of it, or one for sale.

$1200 wow what happened?

THe case cracked and the tranny fluid ran out, did not know it until it started slipping, tried getting it back home, needless to say it did not make it.

I might be able to post a pic, if I can find my old ones from a parted out truck. You might want to go out to the junk yards and start looking. Good luck as most are gone or they do not know what they have...

it is actually known as a torque bar. it ties the tranny to the xfercase, as aluminum gives pretty easy.

Cucvs -all M1009 0r M1008, 1010, 1031, 1028 were never equipped with these braces. Most civ units did not have the TH400 but were equipped with TH350

My m1008 does have one - i bought the truck from gl. I have a m1028 that does not have one. Looks like it never did. Also have a m1009 - looks like it never had one . I have a 1988 4door crew cab air force truck - it does have one. All civilian chevy 4x4's with auto trans 350 or 400 transmission had the brace and 2 small torque rods on the bottom of the bellhousing from 1978 thru 1991 for sure. The older models had a brace that bolted to the frame.
THE TRANSMISSION CASE IS A HD CASE AND HAS A ALUMINUM BELL HOUSING DUST COVER

no k30 ever came with a th350... my 3/4 ton Suburban had a th400 and a torquebrace

but just looked an i dont have that brace on my m1008 either.

all civilian chevy /gmc 4x4's with auto trans th350 or th400 - did not say that k30 had th350

also the brace in my m1008 is not oem . So i know that the m1028 and m1008 that i own did not have them .

Ok.... so I guess we don't need it.

what tranny was this?

PWB, do you have all those Chevys here in WPB? If so I'd love to take a look at them.
