Who\'s cut there 700r4 shaft for the doubler???

Well who's done it??? One guy in our club did it to put a 205 behind a 700r4 with a TPI 350 in four runner. Problem is i don't know the reliablity because everything breaks first on it. I know someone has done it. My plan is to put the doubler in behind the 700r4 ,d60 front, 144ff rear, and either 38.5's or 42's. What do ya'll thinke??? Thanks - Doug

Should not be a problem because that is what Steve is running in the ORD rig behind a stout bigblock.

Yeah, I wouldn't cut the shaft either. You could either get a new "short" style shaft and swap that in, and that'll make the R4 look like a TH350 to the 203....or, I've heard this done and think a couple members did this, but make an extension of some sort that the TH350/203 version adapter bolts up to. Like a donut that is 1 1/2" thick or so. Use that as a spacer, so the 203 will mate to the R4 without change to a shorter shaft.

I bought the short shaft kit to mate the 700 to a NP205 (originally a Th350 to NP205). I would not cut the shaft (does not leave a whole lot of spline). You can run a spacer, but in short wheelbase pickups and blazers you may run into a problem because the 700 is a longer trans and the doubler will take up precious inches. A rear CV would almost be a must (a must if you combine a suspension lift with everything else) unless you are running a longbed pickup or crew-cab and even then if you had a big enough lift a CV would probably be the only way to go.
As to the original question. Yes you can cut the shaft on a lathe, but I would not advise it (just my opinion though).

My trans is running the "built for it" output shaft, not a cut shaft. A spacer would work, and you could cut some of the shaft off, but buying the right one is pretty easy to do too. You don't want to cut off enough shaft to run it with no spacer, you need a little over an inch of spline to be safe. I'm on my second TH700 with this shaft with no problems and the first one doesn't even show any wear on it.
