The front is most likely a d30, but there is a slight possibility of a d44.
The rear is most likely a d44, but there is a slight possibility of a d35. (guess they were clearing out some over-stock inventory...)

I used that graphic last night and took a look. I do have a 30 front and 44 rear.

I'll also see what the rpm's are today on the highway at 70 with the OD off.

thanks for all of the help! Also requested a build sheet from jeep as well.

let me know when you are at chattfield, i ski there sometimes!

 

Actually, the OD off calc will help with the 35's, not so much with the current smaller tires.

ex.
Currently running 3.73 and stock 32's (with an actual measured height of 31")
3.73 & 31" = 1953 rpm @ 70

swap to 35's that measure 34"
3.73 & 34" = 1781 rpm @ 70

turn od off (divide by the OD ratio)
1781 / .69 = 2581 rpm @ 70

swap to 5.13 (with od on)
5.13 & 34" = 2450 rpm @ 70

So with 3.73's and 34" actual height tires, turning OD off will give a decent indication of what 5.13's (actually 5.38's, but not available for the d30) will give with OD on.

This does nothing for you around town or offroad, it just raises the rpm's at freeway speeds to a much more usable level, and is worth considering in the decision of gears vs tires first.

 

Finally got my build sheet. 4.10 gears;

DJRS Next Gen. Dana 30 Solid Front Axle
DMFP 4.10 Rear Axle Ratio
DRZS Next Gen. Dana 44 HD Rear Axle
DS7S Conventional Differential Frt Axle
DS8S Conventional Differential Rear Axle
