M truck currently has an 8.8 that works fine. I have a 9 inch available. The truck is going to receive a 4 inch lift in front with shackle reverse in ther rear. Going to probably run 35's. Question is do I put the nine inch in or sell it to help pay for gears in the 8.8. How much stronger is the 9 inch over the 8.8. I know one downfall of the 8.8 is C-clips. Having trouble deciding which one to use. Any suggestions would be apprciated. Oh, I am also going to be running an Aussie or Lock-Rite type locker in the rear.
