Rear Diff Drive angle

[faf]

I need help with differential vs driveshaft angle. I have a Spirit Industries 23T chassis and suspensionI'm about to order my drive shalt but before I take measurements does anyone know what is the proper angle and how do I set it, If change is needed. currently the differential input shaft sitting at 0 deg from horizontal ground and the trans output shaft is about 9 deg down from horizontal. The dive-shaft is going to be about 19-7/8" long. Any help would be appreciated.

Never set up a pinion angle on a T bucket but have on a few trucks I have lowered. I try and keep the pinion angle to driveshaft around 3 degrees-- that would be the angle of the driveshaft will be three degrees down from the trans and three degrees up from the rear end pinion= 6 degrees, So I would start by adjusting your radius arm on your rear so the pinion angle is 6 degrees below level, should be good right there IMHO

Started to write it up, but changed my mind. Just read the Dana Spicer guidlines here: http://www2.dana.com/pdf/J3311-1-HVTSS.PDF

This is great info and should be put in the Technical pages, as everyone has at one time inquired about this at one time or another.
