Dual t-cases eb dana 20/4:1 Klune V or just Rubi rock-trac 4:1 with an auto XJ or other???
With my quest of getting the gearing options I need/want for my XJ. I have come across some good deals and have to decide which patch to go down. I got a Rubicon rock-trac t-case with 4:1 gearing that is the same length as a 231 with SYE that I could use with my hp44 5.38 /9" 5.43 gearing. I also now got a used Klune V for a good price with 4:1 gearing and can get a early bronco dana 20 t-case that's driver drop for cheap. I have an auto tranny in my XJ but I do plan on doing JV trails as well as the usual by my house Rubicon and Fordyce. What case/combo would you guys suggest? I want at least a 4:1 t-case gearing, with the 20/klune combo I'd be around 150:1 crawl ratio with my auto so maybe close to 300:1 with the torque converter. Who has run dual cases in a XJ? I'm closer to the early bronco/f-150 or so with my hp44/9", dana 20 t-case etc, so the XJ drivetrain is not a factor as I've upgraded from the weak 30/35, 231 etc.
Early Bronco dana 20 t-case with the 4:1 Klune V link, this combo is 18.5" long, just 1" more than the 231 with a SYE (18.5 vs 17.5). You can also add twin sticks to the 20 and have front wheel/rear wheel drive etc etc. I did my research and got all the parts, now I just need to decide what combo to run. Here is a link to the 20/klune:

On a side note, people that are considering the Tera 4:1 kit, don't, I got my Rubi rock-trac with 4:1 gearing one ebay for $1K, strong in all areas for $1K and it's bolt in, or just a little mod because the Rubi case is so beefy and big, but it's length is the same as the 231 with a SYE.

I know tough decision, I found the stuff for good prices so it makes it even harder. I got the Klune V for a good/cheap price, the dana 20 for $150 with shifters and yokes, and the Rubi rock-trac for $1,050 shipped. Please take this into mind with the vote as well as what is needed/wanted for gearing a auto XJ on tough stuff like Johnson Valley trails and moderate trails like the Rubicon and Fordyce. You can also add twin sticks to the dana 20 to get front/rear wheel drive, nice mod on the trail. I will also be driving this jeep to and from stuff, this isn't my dd, but with the 1:1 gearing in all the t-cases that is a non-factor as well. I have a hp44/9" with 5.43 gears and alloy shafts so my axles should hold up to whatever combo. Please advise people, and think about these options for your own rigs, the Rubi case is very nice and now that it is out there, I think the Tera 4:1 kits will not be bought as much. Sell your stock 231 before you do the SYE and 4:1 and save big and be alot farther ahead with the 241 Rock-trac. Just a though, now I'll go. :gag: :laugh3:
