    I do not know if it is just me but the 5 speed in my 95 F150 with a straight six seem to have a better over all gear ratio between gears than the NV4500. I am only running BFG 33 " I need to have my local drive line shop drive it to see if they would recommend a rear end gear ratio change. I think some nv4500 have different ratios between the gears.

    @bucket do you know if a dodge nv4500 can be used as well or are there shaft differences?

    I'm certainly not an expert, but I believe the input shaft is different and the output shaft has a different spline count.

    Dodge vs GM are different diameter and spline. The shafts can be swapped if 95 and later.

    The 92-94 GM are different than the dodge. After that they are the same. 2wd vs 4wd doesn't matter as far as shafts. A 4wd will have a different rear tail housing. 4wd bolts to a 6 bolt round pattern t-case, 2wd has a slip-yoke tail housing.

    When I was researching doing NV4500 swap into my 77K10 I found that AA has a great tech page on the NV4500. May help you out.

    By far the easiest solution is to call Advance Adapters and tell them what you have. They have complete packages. Everything will be new and/or rebuilt. It's not the cheapest option but it will save you months or years piecing it together and rebuilding used parts.
