View Full Version : driveshaft for 9" setup

09-05-2007, 11:38 AM
I just installed a ls1/t56 in my 87 iroc, which uses the same length driveshaft as the 4th gen car as i originally had a ls1 alum driveshaft it it. Im putting a moser 9" in the car this weekend. What are you 4th gen guys doing for driveshafts with the 9". Do i need a custom one made or will a u joint fix the problem? I know i have a different car, but my setup is the same length as a 4th gen so the fixes should apply.

u can get u joint conversion from napa. Napa pn# 240-0447. Since the 9 inch comes with 1350 yoke and the factory driveshaft comes with 1310 yoke. or u could just get a pst 3.5 alum driveshaft from epp. i bought my 3in steel driveshaft from driveline specialties.
