RAT Raceway

Well twist my arm... Under the hood. In the back... Inside... Looks like I'm off to the world of 2wd... But not 100% yet.

Thanks! I talked to his buddy! No plan to remake a output shaft just for a few TBSS'. Understandable for sure. So that lead me to this post on the NV149 here. Looking more and more like 2wd is the way to go.

Thanks for the warm welcome! WOW! Didnt even think about turning. There might be some of that for sure... Right now I'm making 800awtq at 3200rpm and the 4L70 just cant hang on... The stock transfer case should hold up better then an NV149 but there is no way to mate them without a turned down 4l80 output! Guess there is no easy way to go!

Hello All MY First post here. I am a TBSS owner. I'm geting ready to do an AWD 4l80e swap. The TBSS uses a NV120 T3 Torsen transfer case. No one has ever push one HARD that I can find, but have been told the NVG149 can take BIG power. There are other issues in using the NV120 as well... Who around here is lay'n down 1000+awhp and is holding up? Are there upgrades that can be made on a NVG149? Thanks Ross
