I wasn't just curious about the orientation of the drop...but also the size of a d300 compared to a 231 or 242. I know atlases are significantly smaller but I wanted to avoid spending the 2500 for twin sticks and 4:1

EDIT: the only reason this is raising some concern is because I hear alot of problems coming from rubi owners with the larger 241's.

The 241 fits fine, it was the 42rle that was tight

A stock Dana 300 fits fine with the UCF 1" skid. I ran that setup for close to 3 years. I wasn't able to run a front drive shaft because of clearance to the bell housing and the starter. My 300 was clocked to roughly what TJ Tcases are, not how CJ Tcases are.

As others have said a 300 fits in the spot and is nice and short for your rear driveshaft but there can be front driveshaft clearance issues if try to clock it flat.

What do you mean an Atlas is significantly smaller?

IIRC, an atlas 2 speed (like the dans 300) is shorter than an np231 even with a ss sye

Length is very close in those two situations, but overall size of the Atlas case is much bigger and can be a challenge to fit in the space if you've done a tummy tuck (since that's the subject of this thread).

Did some quick research and AA has these measurements:

LENGTH COMPARISON:*Atlas Short tail 11.8" NP 231, 20.5"*Atlas Long tail 13.8" NP241 Rock Trac T/C, 15-1/4" Dana 300, 12"
Im assuming that's a 231 without any form of sye...

From the faq section on their webpage:

Length is not the issue, its height that causes problems

Yes, that is the 231 stock. I think with regular SYE 231 is about 16.5" and with an SSYE is around 13.5".

I think the number they are quoting for the 300 is the short tail one. Most I thought were the long tail that adds something like 1-1.5".

With respect to the Atlas, as I said before its not length thats an issue. It is the overall size (height and width) of the case that can make it interesting.

Right, my main concern was with overall length of all them and the overall size in general of the d300, I don't plan to move the rear axle back more than 3 inch to try to stay maneuverable for the trails around here that I run...that combined with not too man hill climbs but a lot of ledgs and rock gardens means I wanna tuck my drivetrain up as much as humanly possible

Are you relocating your gas tank/going to a fuel cell? IMO there is pretty close to zero room to move the rear axle backward without doing that.

I was banking on there being no room to move a 14b back, even if im getting rid of a trackbar because of the switch to a double triangulated setup, and simply relocating everything to inside the tub (similar to what flatlander757 did with his build) and using the backseat (which is already pretty stained and beat up) as garage furniture...

EDIT: killing two bird s with one stone by gaining a lot of under clearance and room to move the axle back

Quick question with the ucf vs savvy skid plates... I noticed that the savvy doesn't have a hole in the engine/tranny skid for the oil plug for easy access. I really don't want to have to drop the skid every time I wanna take a look at the oil pan or want to change it. So for this reason I will probably go with the ucf engine/tranny skid if I don't hear anybody's input.

Mine has a port with a removable door, for oil changes.
