    I am going to be doing a doubler in a few months and I am going to run the Exact 1.5" spacer so I can put the 203 on the back of the 700R4. Will this extra 1.5"'s cause a problem? I will be shortening the wheelbase to about that of a blazers. So basically the question is: those of you with doublers in a blazer would another 1 1/2" cause a problem with the rear driveshaft being to short? I will be putting in one of Jesse's CV shafts. Thanks

    The first Gen Doubler was the longest of all because it used roughly a 3" aluminum spacer, plus a factory adaptor which was about 6". Meaning, the Gen one doubler was 6" longer than their current configuration. I know of several K5 owners who use these with 6" and above lifts and have no problems with driveline issues.

    I clocked my NP205 up to flat - meaning my inputs and outputs are all level. Mine is behind a TH350 and the driveshaft lengths are 35.75" front and 36" rear.

    I don't think you will have problems with driveline if that answers your question. /forums/images/graemlins/thumb.gif

    I'll tell you one thing - I love having 4:1. I might regear to 5.13 someday.

    I don't think that would be a problem.

    Ideally, you could "adjust" your WB (if your redoing it anyway) so that you can have the same length drive shaft front and rear (buy 3 at once, two for the rig, one trail spare).

    that is the ultimate goal IMHO

    Yeah that would be the bast way of doing it, but wouldn't that ammount to the rear axle being pretty damn far forward? Meaing a really short wheelbase? Later

    Not hard w/ the doubler. Keith is off by about an inch (close enough make it up in the splines) his wb is around 109-I think
