8-3/4 cap studs

[Paul Secoy]

Hello all, I seem to recall at one point in time a stud kit was available to replace the bolts in the caps of an 8-3/4" center section. I swore it was ARP that offered them, but I have looked several times and cannot find them. Did I imagine it, or do they exist?

Thanks

Wrong bolts You differential cap bolts correct?

I am looking to replace the 4 large bolts that hold the side carrier bearing caps to the center section. I thought a stud package was available at one time.

Maybe try Dr. Diff

Even if you don't see them listed, contact Cass about them. He'll definitely treat you right!

ARP had one available 2 years ago when I did my 8-3/4.

Not sure if they still do.

I bought it at summit

It'll break other parts far before the bolts. 20 psi boost on the trans brake with drag radials will make a nice 2 piece pinion.

Thanks for the information and recommendations! I thought it might help keep stuff from deflecting quite as much, not so much worried about the bolts themselves, The spool and yoke I am using are being recycled from a busted set, the outer half of most of the ring gear teeth are chipped, I assume something tweaked a bit more than it was happy with, bolts were fine. 9.0 pass on a heavy car, so its next life will be slightly gentler. Just thought it would be $20 worth of "feel good", lol.

Grade 8 1/2’ bolts are what is used, but I forget the length. Studs would be perfect, maybe the 9’ uses the same?, if so, I’m sure they are easy to find.
