Default 05 Rear Diff

Hey guys, need some help. I have an 05 z51 manual 3.42 rear end. i blew the rear diff. From everything i am reading, the 05 was the only year they used an inferior rear diff. i believe they beefed them up in 06. I am having a hard time trying to find out what will work to replace it with. OEM is like $3500. Can i use any rear diff that is a 3.42? ive seen a Z06 rear diff, which i think is 3.42. Is there any other modifications if i go that route? OR if i get a 06+ are there any other parts and pieces i would need? Thanks in advance.

You might try RPM Transmissions. They could probably set you up with everything you need.

When my son blew the diff of his 05 by dumping the clutch at tree of our local drag strip, I had Stephen at England Green (best vet shop in Houston) replace it with RPM Stage IV with Quaife. I also decided to go with 4.11 gears that really woke the drivetrain up!!!!

Contact RPM like mentioned above by CS, I think I remember that they had to supply a bracket (not really sure about that part) to be able to install the 2006+ assembly but it has been years now.

I just looked and the prices have elevated quiet a bit since my install but I love that I don't have to worry about weakest link of the 05 drive train any longer.

Good Luck!!!!
