[4l80e Nvg-149 32 Spline Input Gear Adapter]

Looking for one of these adapters for a 4l60 to 4l80 swap into a 2003 awd ss. I can't Pm Time2kill if anyone knows how please let me know.

[4L80E AWD]

I'm the guy that makes the input shafts for the t-case.

 

I've had guys running over 1600hp thru these, and have NEVER had a single failure.

 

Ask around about turning down the output shaft, you'll find several failures pretty quickly with much less HP.

 

Are these input shafts still available? I'm looking into doing a swap out and upgrade to the 4L80.
