Driveshaft .. a judgment call.

[XLexusTech]

Pre prerequisite. current power .. 495 Hp and 473 ftLbs torque.
Likley in the future.. magnuson supercharger and cam swap. target 640 ish HP.

Problem.. my 9 inch has a 1310 yoke...

Option 1 just order the 1310 driveshaft it will be fine at 600 Hp/Tq numbers .. Lots of folks are running this says the all might internet..

Option 2 order an 1350 shaft then install a "hybrid joint"
will require a new pinion yoke which may not be the same length and make shaft useless ..

Options 3... change pinion yoke now.. (not sure if on a 9") this-is just a replace or could impact bearing load ect.. and order a 1350 shaft.. now..

I would call Dynatech driveshafts and ask them. They can run through the numbers and tell you what it needs what if it’ll be strong enough

Call Mike at Dynamic Drivelines. My custom 3.5" carbon fiber driveshaft was less than $850!!!! It is just him and his wife so he keeps the costs down. He knows his stuff!

Thoughts on the driveshaft shop vs dynamic driveshaft? Driveshaft shop balances them to 9000rpms. But it seems dynamic is cheaper as well
