Hey guys, searched the forum. I’ve got a new in box locker for an ‘89 c1500 project. I’ve seen you can use that on my 2002 Sierra 1500 while I add 4.10s to it. Do I need anything else to do that? Install kit needs to be for....the 8.5” even though it’s going into the 8.6”?

 

I think the only difference is the carrier bearings.

 

Ok so snag carrier bearings from an 8.5" then to use in the 8.6"?

 

madmann is correct. If you call or email Randys Differential they'll fix you up with the correct bearings for your setup.

 

ahh! you guys are awesome, ill reach out to randys differential and get it all set. thought i was going to have to sell this one an buy a different one for a little phew!

 

I used 'Randys Differntial' or Randys World Wide last week for a ring gear install set-up. great pricing, help and fast shipping
