12 bolt ring bolts


Do you reuse the factory bolts if they look perfect?

Or get new ones? If the answer is new what manufacturer? Part number?

Thanks

I'm not sure what others here will say but I've never installed new ones, and never seen a broken one. This is just for a street car, not a drag car?

I'd reuse them unless you'll be drag racing.

Or change them anyway for peice of mind,

As long as they look great when they come out

I would think to reuse them BUT when I watched 

the Haggerty 12 bolt rebuild video Damian (I thats his name)

ordered the wrong bolts then ordered the right ones I think 

anyways my point being just wasnt sure what was accepted 

practice

 I have all the parts now for the 3.42 Detroit Locker upgrade

and just got to thinking about the ring bolts?

Thanks for the advice!

I reused them in my 2 12 bolts no probs with Eaton style carriers. Maybe certain carriers need a special shoulder on the bolt?

 3.42 is a really nice compromise gear. 3.31 is on the tail end of performance and 3.55 is getting a bit much for high speed highway driving (unless you have overdrive). It's a shame GM never made 3.42 for the passenger car 12 bolt diff.

 Interesting, that they didn't have it. But, agreed on the 3:42 for best overall - I changed from the 3:31 to 3:42 and it made all the difference by eliminating a slight lag in the OD (700R4)

3.42 ratio was available on american Pontiacs. Eaton 8 7/8 12 bolt diff with a 10 bolt cover. 1965-70.

And once they came out with the 8 1/2" in GM's early 70's vehicles it was a very popular gear.

The tensile strength degrades after theyre first torqued, but as long as they arent subjected to loads outside of typical street driving, reusing them wont be a problem.

If the engines been juiced, or the car will be track- or street raced, fresh Grade 8 bolts are cheap insurance.
