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.

I'd say 9" if it is a big bearing.
or go right to a sterling 10.25
I agree, go 9" My 8.8 didn't last long with 35's

On the other hand I have a sterling 10.25 f/s

The rear end is in an 86 f-150 with a 351. I don't know if it is big bearing or not. So from the responses so far it looks that the 9 inch would be the choice of the two. Would love to go to sterling but I already have the 9 inch.

I believe all the truck 9" are big bearing, though I'm not certain on that.

I am pretty sure nate is right on that one except for some old 70s fullsizes I have seen, I think these were 2 wheel drive and they were narrower than other fullsize axles. The two trucks I was looking at were both 71s
