on the Nissan pickup whats the gear ratios for the diffs and is the diff the same outercase as the soob?, I know the axle shafts are beafier and bolt up with flanges , the case looks similar, if the ratio is the same as a soob I was thinking of running a front nissan set up in the rear of the soob , also whats the ratio in the transfercase? Thanks Scott

why not just run the solid rear? it would be stronger and probably easier to mount.....

I guess you've never seen a Nissan front diff before. Fabbing a solid rear is a bit more work than setting a front diff in the rear.

 

Scott, the ratio's are 4.37 and 4.62 The front diff is a R180. Slightly larger housing. I am not sure if the overall dimensions are the same though. It may bolt up. A LSD center won't fit though as it is smaller than the Nissan center. I don't remember what the transfer ratio's are though. Sorry!

The transfercase ratio is 2.02:1 in low, and 1:1 in hi. That's for all the years that use that 'case. It's like a T102 or somthing like that. I found info on it by Googleing "Nissan 720PU"
