I am looking for options to increase my crawl ratio, are there any reasonably priced ways to do a dual xfer setup? Currently I have a dana20 with an anemic 2.03:1, even with regearing it would onyl go down to 3.15:1, so I need some other options... Thanks Kornchild

well the 3.15to1 isn't all that bad with an auto. just gear the axles accordingly. if that isn't good enough the best option would be go atlas. you get more gear, dual sticks, and a case that is alot stronger than the 20. just my op.

I guess you already have the TH400. However, if you don't you could look at one of the Jeep Torque Flites that had the D-300 and then put 4:1 in the x-fer case. A TF-999 with a little tweaking probably would be okay for a stock 304.
