yes contact teesee150 the company he works for make them ive got an 80 and awd in my 03 ss

 

The binding is avoided by the use of the viscous coupler, it is not hard linked like a true 4WD.

The 4l80e Nvg-149 32 Spline Input Gear Adapter is available from a gentleman on the SS site (same fellow who has the TruCool brackets). They are from EAD Performance.

A small amount of what he posted on the SS site:
I've been selling these for quite awhile, but I don't think anyone really knows about them. Chuck at FLT has been using them for a few years with excellent success. We have had them in several 800hp+ Silverados and Escalades that have swapped to a 4L80E with the NVG-149 Transfer case. Not a single one has failed yet unlike the turned down output shafts for the 4L80E.

This swap is very easy to to do. You just need to take apart the stock transfer case, pull the input gear out, and put this new input gear in. Takes about 30 min to 60 min depending on your skill level.

I sell these for $325 + $80 core for your stock input gear. I have several on the shelf ready to ship. I can also sell a complete Transfer Case with this installed, or you can send yours in and I can perform the install for you.

 

Billy, of course when u can switch off to 2WD, it'll give better MPG. No assuming about it.
Don't worry, u don't need AWD, you're not gonna be makin enough power.

English?!? 6 of one, 1/2 dozen of the other. :nunchuk1:

 

Thank you sir!

...not yet...

 

nice avatar fastnblu those are big ****

 

Those things can cause you to become hearing impaired, especially once your face is planted between them.

 

Not later either.

Thanks, I like em. I've got a soft spot for big ****, always have.

1Bear, if I had been on a 3-legged stool, I'd a fallin off w/. your comment.
I knew the viscous coupling splits fore & aft, but can it control slip in a side-side orientation as well?

 

awesome info guys thanks alot. whats the going price for a NVG149 transfer case?

 

Beings the front differential is an open diff, the front tires can and will spin at different speeds and due to the front having a higher wheel speed than the rear when turning, that’s where the viscous coupler comes into play by letting one end of the truck have different axle speeds. Another cool thing about the coupler is under normal conditions it runs at a 38/62 split when distributing power, but can send more power, up to 100% to one end if traction is lost. It does take a split second for this to take place and under wide open power there can be some hopping around, especially during a launch at the strip.

 

about how much does a NVG 149 transfer case cost?
