Hey guys, so I finally found a core nv4500 for a good price to put in my truck. My question is regarding the transfer case. I have the 23 spline 205 from behind my auto, I found a 29 to 23 spline adapter coupler from shsdiesel.com, will the 23 spline t-case hold up behind a stick? My goal hp number is around 300. The reason I ask is because the coupler is much cheaper than buying a 29 spline 205. What are you thoughts, anyone used one of these before?

 

call 1 800 776 1191 tx exchange, if the part is weak, they will recommend a input gear

 

You will be fine with the 23 spline transfer case, the one in my brothers truck didn't break til about 550hp, and while sled pulling.

 

was it hooked up behind an auto or a stick though?

 

It was behind an auto.

 

yeah. I would venture to guess he'd be fine but there is definitely a reason they went with a bigger input for the stick trucks. An auto will dampen things and be more gentle, if you will, than a stick ever would.

 

Yeah, I know they went to a 29 spline shaft for a reason and that a 23 spline behind a stick wouldnt be "ideal". I just figured the 23 spline t-cases seem to hold up fine behind a built auto just fine, even ones with a lockup converter, until you start getting into some crazy horsepower/torque numbers. So I figured if I could save some coin it would help me get the truck on the road sooner, and in the meantime I could keep my eyes open for a good deal on a 29 spline case for down the road. I probably wont be out at the track hooking up to a sled anytime soon anyways.

 

As long as you're not out drag racing or dumping the clutch I don't see a problem in it.
