Re: 88 iroc rear end question
Thats true. the 2.77 is a 2 series carrier and you need a 3 series carier to install a bigger gear.

Re: 88 iroc rear end question
go to advance auto parts and go buy a gear spacer it will make it a stage 3 carrier i did the same to mine i had a 2.73 gear then went to a 4.11 and used the spacer works great.
