If you are running 30 spline axles in your 12 bolt (93-02 f-body style) and have ever considered upgrading to 33's, shoot me an email. I'm interested in buying your 30 spline axles. I just got a great deal on an Eaton posi with two sets of gears so I'm looking to buy a 12 bolt housing and build my own 12 bolt.

Let me know if you got a set laying around or if you have future plans to upgrade, maybe we can work out a price.

So,,,,, nobody in the PNW is pushing limits of the 30 spline axles on the 12 bolts? You guys need more nitrous or boost or what?

Just kiddin'. Just trying to drum up some responses..

Already got 33 spine axles in mine.

 

I have 35's

 

too bad ur not making enough hp to break 28s

 

I had 33's on a 82 GMC shortbed once. Had a 4" lift too.

So everyone with a 12 bolt has the 33's or is perfectly happy with the 30's?

"too bad ur not making enough hp to break 28s"...*** munch...400hp + 3600 + Street Twin clutch is MORE than enough. The way you lauched your car Payam, you could have had Sunbird axles in your 12-bolt and not break them
