Can I just buy 4.10 gears and take them to a shop and have them installed, or do i need other stuff?somone told me that you cant just put 4.10 because it requires a 4 series carrige,and that cost 800 bucks he said. So he said if I want gears the hightest I can get is 3.90 because its a 3 series carrige that is have. What is he talking about? cant I just buy the 4.10 gears and take them to a shop and have them installed with no problems

The guy's smokin dope, you don't need a different carrier for 4.10's ... you should get a different speedo gear to set your speedometer right though - might as well bring em some gear oil and friction modifier too

Like MD said the guy is on dope. I don't remember anything about carrier breaks on a 8.8. I'd get a new set of bearings and races. Your going to have the thing all apart, may as well freshen it all up.

I think he was talking about GM carriers, because my friend who has a 94 Z28 had to get a 3 series carrier to get from 2.73s to 3.73s. He must be a GM guy thinking he knows everything and everything that applies to GM MUST apply to Ford too.

something like that....He has a 90 GT and it has a 331 and runs 11's, anyway can i just buy gears and take them to a place to have them installed, Do I need bearing or shim kits, cause ill just buy 4.10 gears and have the mechanics put them in.

When I did mine, I bought the gears, a Ratech Deluxe Rebuild kit, Traction-Loc rebuild kit, and fluids...

Like I said before...that story is BS
I would highly recommend buying a new trac-loc rebuild kit because yours is most likely shot or you'll be doing one wheel burnouts.....not good.
I bought the kit from Summit for $50. Also, get new axle seals too.

Jeeps also have carrier breaks.

Get a master install kit. It will have new bearings, races, shims and seals. Also a rebuild kit for the lim slip. Done.

well the 3.55's in my car were installed recently before I bought my car, so the trac-loc is newer, and the rear was recently rebuilt, so I think ill buy just gears.

if your going there and dont want to go there again i would replace the clutch packs in the posi unit, do the bearings and races nad get that pin and gears and you would never have to open the cover up again
