If you know of anybody into 4 wheel drive and they happen to have a
 Chrysler Rock Trac 4.1 transfer case apart I need a cell phone
 picture of just the planet carrier.

 I have tried just about everybody and every thing here in SoCal. No
 luck so far. Some of the catalogue pictures are wrong like this one.
 Apparently Chrysler uses generic part pictures and not actual part
 pictures.

 Paul, maybe call JB Conversions 337-625-2379

 Lots of data about the older New Process 241J and the current
 NVG241OR (as used in Rubicons) which have 4:1.

 There is also a conversion kit that replaces the front half of the
 case with a 5 pinion 4:1 set

 Bingo David!!

 SO that's how they do it!!!!

 EXACTLY what I was looking for.

 Now I got to go see how big it is.

 It looks perfect. It even has a prop shaft spline. Essentially double
  planetary's but lighter in weight than two separate planetary's.

 I don't see the ring gears so they must be built into the housing. No
 problem.... we will just cut away what we don't need.

 Thanks a bunch for this David. This is THE key to the Reno Racer.

On the regular 241 the ring gear is press fit then held in with a big
snap ring, if you heat the case it'll come out.  I've never actually
seen a Rock Trac, I didn't know it had a special planetary like that,
interesting.  It seems like torque capacity would only be about half?

That is good to know Everett.
I was worried about it.
Is there just one ring gear or two?
Some are six pinion and some are four.
Hopefully it is six.
