Upgrading the 9-bolt
Upgrading the 9-bolt
Hey, I know the 9-bolt is hard to get parts for but is there a place where you can get upgrades for it?? I'm already putting close to 500 hp to it and it's held up pretty damn good so far, but i plan on doing some other work to the motor and feel i should start to upgrade the rear. It's a street driven car so it's not like i'm launching hard on it everyday but when i do i'd like for the strength to be there. I'd rather not replace it with a 12 bolt or a 9in (which i know is a good idea) but i'm trying to keep my cost down as much as possible so i can keep up on my other projects. All i'm looking for is stronger axles, different gears etc.....Thanks

Re: Upgrading the 9-bolt
On the group purchase board there's a thread for the TA Performance rear end cover. I got mine and its a nice piece. And a few places to get gears have been posted a few times on this board. Try searching for "9-bolt gears" or "9-bolt axles."
