can seem to find or get the info I want from strange my question is the ultra case longer than there regular alum bolt thru 3rd member. I the pictures it def looks longer. my issue is I have a regular 3rd member want need to upgrade and change gear with the new power but don't want to have to replace my alum driveshaft if at all possible.

Wouldn't it be dimensionally limited by the gear set and axle center line to be in the same spot if it is still a 9" ring gear or am I missing something?

Some of the ultra cases will not fit into certain housings. I was going to do the ultra in my HT.
It will not fit. It is too long. I believe the ultra is 18x15x13. My driveshaft/coupler is only 5.75 long. You have to call them or an attempt the email. I can only use the Pro HD case due to minn room i have. Here is a PDF on a warning about grinding the case.
