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..
