what are the differences beteween an 01 z28 and 02 ss rearend. mechanic says 02 is bulletproof but i have found an 01 for a cheap price? are they the same or even close? im on a tight budget here trying to get clutch/differential and headers done .

 

as far as i know they are the same, may have a different ratio.

 

93-02 F bodies were all 7.5/7.6 GM 10 bolts with the exception of a few SLP cars that got a 8.875 12 bolt, but these are so rare, you can't even laugh. If your mechanic thinks the 7.5 is bullet proof, I'd find a new mechanic. They are fine for stock application but any extra power and they become a ticking time bomb, especially with a M6 and slicks. Otherwise, the 01 and 02 are the same, and if you're on a budget will do the job just fine.

 

2001 Camaro Z28 whole/parts that is the rearend i am getting for $150. is this better than my stock 94 camaro rearend? should i wait and save to buy a 8bolt or 12bolt

 

It's not any better nor any worse than the 94. The only two things that changed between 93-02 rears was whether it had 3 channel abs (sensor in housing) or 4 channel abs (sensor at each wheel) and the rear axles on '97 and later models have a smaller center hub diameter, but that doesn't hurt any thing. Otherwise, they are exactly the same.

Unless you plan on putting down lots of power, the 10 bolt will be fine for your needs. My '93 has all the bolt ons and is cammed and hasn't broken the rear yet. But I'm also an auto. Keep the clutch dumps to a minimum and don't run slicks and the 10 bolt will last.

 

pretty sure the center section changed a little somewhere along the line. clutch style in it i think was upgraded,,, if that last brain cell is working

 

You're right Craby. I forgot that. The earlier years had a clutch style LSD while the later years, I believe 99 and up, had the torsion diff. They both have their advantages and disadvantages though. Basing strength off a of the ring gear though, they're all 7.6inch rings, so they're all just as weak as the next one.

 

what about the rebuild thread to .handle 450hp building the 10 bolt up .thread craby posted ,thats . the one i plan to go with ,for about $400..00 to $600.00,alot less then a ford 9 ,or moser,??? right at the top of this section strethening the 7,5 10 bolt

 

i fried the cone one i had right away. turned into a one wheel wonder. had issues just getting going,lol. leaving rubber everywhere.

 

I did the upgrade on the 7.5 on the Olds bracket car. Found a 2000 torsion posi unit for a $100 bill from a guy that said money talks and BS walks. This guy was as done as a box of rocks but I came out OK on the deal. I then up graded to a set of GN 28 spline axels and a reinforced cover for the back. It handles any thing the 383 stroker put outs on a set of DRs. Those rears are stronger then most people give them credit for. I don't think I would want one for a stick or trans brake car on slicks though.
