Is there anyone out there that has upgraded their rear end. I have a 6.6 pushing 700 HP to the wheels and I’m looking to put 37 on my truck. I know my stock Rearends will die so I want to get ahead of this issue. I was looking at the Currie 9 inch but it looks like they bypass the lockers and I would really like keep my rear lockers. I’m thinking of 5.13 gear ratio or possibly 4.88. Please advise....
