Title: rubicon case
Post by: DirtyJeep92 on November 09, 2014, 01:05:56 AM
Long shot but if anyone has a Rubicon transfer case out of a tj they are willing to part with I'd be interested. Or if anyone had any leads

This will be cheaper than finding a rubi case unless you find somebody with no clue

Not a 241OR, but a built D300

The pop out issue they're talking about can be fixed easily.  JB Conversions has upgraded ball/spring kits cheap to correct it.

What's your application?

I do not have personal experience with this kit, however I do remember a guys from Hudson NY's club at BTC saying they suck on road and don't last with steet driving.  Said bearings wear out, poor construction.  I have also read this around the inter web.

This is going in my xj with an ax15. And I have the 488sin the diff so next step for a lower ratio is the case.

Another option to consider would be a 231-300 doubler.  With the XJ, you'll have the wheelbase to ensure driveline angles are not an issue.  Here is link to the kit.

http://www.pirate4x4.com/forum/motor-tranny-t-case-performance/696803-np231-planetary-crawlbox-box4rocks-499-a.html

Assuming you already have a 231, you'd be $500 for the kit, roughly $200 for a Dana 300, then another $450 or so if you wanna upgrade the Dana 300 output shaft.  With an upgraded shaft, your total cost would be roughy $1100 (about the cost of a 241OR) and this would be super strong.

This would give you a 2.62:1 (Dana 300), 2.72:1 (NP231), and a 7.12:1 low with both low ratios engaged.  Also, you be able to later add a 4:1 kit to the Dana 300 to give you 2.72:1, 4:1, and 10.88:1 options.

Another option, definitely stronger would be this:

http://www.pirate4x4.com/forum/motor-tranny-t-case-performance/1075295-billet-planetary-doubler-699-box4rocks.html

Then back it with a Ford NP205.

2.72:1, 2:1, and 5.44:1 ratios.  NP205's are huge with stock 32 spline outputs for the ford version.  It doesn't get much stronger honestly.  Price wise, you'd be around the same money still.

The 231/300 seems like the way to go.plus I can upgrade lower gears down the road if need be.  And yes I have a 231 as of right. Now
