I am pulling out the 3.42 rear and going back to stock on my z. This is a 4 channel rear with about 70,000 miles and 10 passes at the track. It is working fine and still in the car if you want to take a ride feel free to come check it out. It has been in the car for about 2 years and i only used mobil 1 oil and GM posi additive. I will be removing it this weekend or nextweek sometime. comes with backing plates and swaybar no sensors. I have a ta cover on it but i am keeping that i will put a stock cover back on. $250 picked up or i can meet somwhere.

Rear is out of car and ready to go. Takes about 4 hours to pull one out and put one in. Easier than changing the gears in the rear.

This was out of a six speed car but i had it in my auto. I went back to 2.73 for the drive to florida and now i only us the car for cruzing with the family. I have the ss to race around in with 4.11 and a 6speed. I dont have the room anymore to store all the parts i have so i have to get rid of one. I am keeping the other 3 channel rear with 3.42 becuase its easier to convert to 4 channel. If sombody wants the rear i can help put it in at my garage i can even help with a pcm tune for the new gears.

Is it a torsen rear? I've been running 4.10 gears in my auto, but I'm kicking around going to something easier for all the highway driving I've been doing lately.

Thats funny I had a stock 3.42 rear end in my V6 firebird!! It was called a Y 87 Package!!


I know that they came in 6 speed cars. I wanted to know what car it was in.. He has both an auto Camaro and a M6 Camaro.

Its not the stock rear from either of my cars. I bought it a year ago from a guy with a six speed car that had 69,000. He was putting in a 12 bolt. I opened it today it has the torsen posi.
