i'm working on a dual t-case for a kick just finishing up some details.   stan

Oh, great.  Stan, I think I'm going to have to move you to Colorado.  Of course, if you had two stock Kick cases, lo-lo would only be 3.24:1, where I currently have 4.24:1 in lo, so that wouldn't be great.  Of course, if I had 1.8:1 and 4.24:1... and put my diffs back to 5.125, then lo-lo first would be over 140:1!

Now if I had Stan's Ford 9" front and rear, with the 5.83's...  Oh, this could go on forever!

We are working a doubler right now. The protype should be done this weekend. I will start a thread on it as soon as I get the cases back. Oh and this is set-up to run a dana 300 on the back. It's a lot of weight but you get twinstick. Should work for both the manual and auto trans. I'll keep you posted!
Dana 300 is 2.62:1 and you can buy 4:1 gears for them pretty reasonable.
Still would only give you 4.7 gear reduction with out aftermarket gears but you should never break it for sure!
