Hey guys, I am looking to replace the crappy stock 10 bolt in my 1997 Z28. It has been starting to make noise, and I really want to start launching the car without worrying about it. Need something that will hold at least 600 RWHP consistently. So something like a 12 bolt, Dana60, etc. Just wondering if any of you f-body guys knew of I hook-up to get one for a decent price or not. Let me know… ---

They need a specific mount for the torque arm. You would need some very good fabrication skills to do a junk yard swap. ---

All depends on your budget. The hottest ticket would be to install a 9 inch Ford rear end. Strong, light & least expensive. A Dana 60 is also solid but very heavy & too expensive for my taste. A 12 bolt GM is also a great choise but also pretty pricy. Look to the rear of any auto mag & you will see both the 12 bolt & 9 inch being built to your specs, gear ratio, posi/lockers etc. Moser makes a great diff, 12 bolt starting at about 1800 including spool. if you want a posi unit & you will need one for road use, they are extra. They also have a 9 inch starting around 900.00 + 3rd member. check out [www.moserengineering.com](http://www.moserengineering.com). I like the 9 inch myself but both are good rearends. ---

Strange Dana S60 is lighter, & takes less hp to drive than a Ford 9". I wouldn’t trust a built 12 bolt. If the S60 was available when I made the upgrade, it’d be a “no brainer”:shrug: Nytrus1 @ pm performance is an authorized dealer, pm me if would like his #. ---

Thanks a lot for the advice guys. I am not in a huge hurry, but would like to get it in there sometime in the spring. As Turbo said, I don’t take my car to the track that much, its mostly street fun. But, when I do take it to the track, I want to be able to really give it a good launch to see what kinda times it could really run. Last year I had to baby it off the launch cause my 10 bolt was making noise, and I wanted to make it home. So which rear end would be the best all-around for that kinda use? My next quest after that will be to try to get some traction. I’m thinking if doing some suspension upgrades. But I am also just thinking to leave the suspension as it is and bring some slicks to the track if I really want to hook up… ---

> [@CrazyLT1](#): > > But, when I do take it to the track, I want to be able to really give it a good launch to see what kinda times it could really run. Right there, that says to me a 12-bolt isnt going to cut it. They are all the same price, or very close in price. You might as well get the strongest, which is the Dana60. With the 9-inch, yes you can change rear-end gears faster, but honestly, who does this in a street car? [Next page](https://forums.speedlife.net/t/rear-end-for-my-lt1/44096.md?page=2)
