4.10 you won't regret it with a 5spd. about the warranty, it should only void your warranty on the gears, but it isn't really a "bolt-on" mod, other wise it would probably void your warranty on your drivetrain and nothing else, but for sucks so they will probably try to void your whole warranty if they find out about the gears. IF they find out. You don't have to tell them you have them. They don't tell you about alot of stuff and they couldn't really tell if your speedo works right.

How about 3.90's? Mine are in the mail, can't wait for the install ... And to answer your question, yes gears will void warranty, but they won't really be able to tell unless investigation is going on.

Call the ford dealership and ask the service department. I heard if they install them it will not void it, but I may be wrong.

I really want to get 4.10's..BADLYY!!!..but with all the problems the 3650 tranny's are having, im afraid if I get gears and the tranny craps out on me I'll have a very expensive bill to pay. And once they drive the car they will def. know it has gears installed.

No it wouldn't void your warranty. If you get a Ford Racing 373 or whatever it doesn't void it. The only thing about that is ford has to install it for u. Anything you get by ford and dealer puts it on goes on the warranty unless it says won't be under warranty.

Looking in the 2003 FRPP performance catalog, let's say we look at a set of 4.10s for an 8.8" Mustang...Part number M-4209-G410. There's an asterisk after this partnumber, like many in the catalog, which means that the part is "not legal for sale or use on pollution-controlled motor vehicles." As well, page 2 of the catalog also has a section about warranty which essentially states "Competition parts are sold 'as is' without any warranty whatsoever." and "Ford Motor Company vehicle and parts warranties are voided if the vehicle or part us ised for competition or if they fail as a result of modification."

So, with the part not legal for sale or use on emissions-vehicles, will a dealer, even an SVT one, install a set of gears on my 02 GT? Second, the warranty wording seems pretty clear: if you modify the car and something breaks, expect a hell of a hassle from Ford in getting it fixed.

I love my 3.90's. Screw the warranty. You want to modify and go fast...throw warranty out the window. My 2003 GT is on its third tranny, second motor, and who knows what else is gonna blow. I don't even drive it that hard. I don't trust those f@gs at the dealership anyway. Took it to get some warranty work done and when I picked it up it had burnt rubber all over the sides and exhaust pipes. Bastards. FoMoCo is a buncha MoFo's. Only I can coat it in rubber.

Thats weird because two Ford dealer said as long as its a Ford part unless it says other wise its under warranty. I guess i should get everything writing these days. Damn it you can't trust no one, all they want is for you to do it to get your money. Thank god i didn't let the dealer put my gear in. I got it all done for 475 with the gear and 2 ABS senser that went out at my friends shop.

Gears will void the warranty on your rear end, dunno about the rest of the drivetrain, though.

If you're on your 3rd tranny and 2nd motor and don't even drive it hard, I suggest you find a better mechanic. I'd say whoever you use now is the f@g. Maybe you should take it to the dealership instead!

The only way that any bolt on can void your warranty is if the dealership or ford can physically prove that what you have installed is a DIRECT result of what cause the failing part to malfunction. So with gears it will NOT void your tranny warranty or anything like that. However it will obviously void your gear and traclock warranty. If you want new gears and keep them under warranty you need to buy ford gears NOT Ford racing they are still concidered aftermarket and a dealership would need to install them. Some dealerships would say that it voids warranty but all you need to do is call ford and complain and them the dealership will call YOU back within a couple of days appolagizing cause they were wrong. Which is kind of fun to here.

amen to that

so lets say you install gears
then throw a rod
those gears are not going to be the cause of failure now are they?
BUT if you break your rear end that might be another story or maybe even axles
but unless the break was caused by the gears themself then you are safe

so just to bring this up again
