Hey everyone i have the 9 bolt 7.75'' rear end in the iroc and i heard from a friend last night that the newer chevy blazers are infact a 7.75'' rear end as well and he says the gears will go right into my rear end??? Any input im looking for 4:11's and i know 9bolt.com has them but there a little pricey....just didnt know if anyone knew if this information was true or false. Thanks for reading- Chris Bystrack

 

Hadn't seen any such thing under Blazers (they look like 7½" 10-bolts to me, but what do I know); however the GTO/G8 uses some variant of that rear, and at least some of the parts interchange. Don't know for sure if gears are a direct swap or not.

 

thanks for the response!!!!
