2002 Z28 Drive Shaft Question

**FOXBAT** · 01-12-2008, 03:52 PM

Just measured out my drive shaft as I was thinking about getting an aluminum or carbon fiber replacement. I was seriously contemplating a 3.5 inch diameter with Spicer 1350 joints and slip yoke.

OEM Length from U-joint center-to-center was 41 3/4 inches.
OEM drive shaft circumference was about 8 inches = about 2.546 inches in diameter.

1) Is it true that the LS1 package already includes an aluminum shaft?
2) Has anyone out there installed a 3.5 diameter shaft? And if so, did you have clearance issues?

Many thanks in advance...

ive got a 3.5" shaft with 1350's in my M5. its a little larger than stock, but still clears fine.

i think the total price of my shaft, u-joints, and both jokes was like $320 shipped. lemme know and ill get you the guys number.

Not all LS1's came with aluminum- only if you had 3.23 or 3.42 rear end- optional on the A4 or the standard.

The 'fuel economy' rear axle came with steel and 2.73's-

i didnt know that the 2.73s had steel shafts. i might need to get an aluminum one now.

To date, the only location that is close to under four bills is Carolina Driveshaft.

So, what's the number? PM me if you can...would be much appreciated.
