Thanks guys, thats good news about the warranty - I'd still like to avoid a conflict, but how often will my rear end come into question - not so often I imagine...

Does this kit include EVERYTHING I need?
http://www.latemodelrestoration.com/...r-End-Gear-Kit

It says it includes:
Kit includes:
1 Ford Racing Performance Parts 3.73:1 gearset
1 Master bearing kit (includes pinion & carrier bearings, pinion seal, ring gear bolts, pinion nut, crush sleeve, shims, and marking compound)
1 bottle of Ford Racing Performance Parts Friction Modifier
2 bottles of Royal Purple 75W90 gear oil

It says master bearing and carrier bearings, is that the same as "side bearings" as the guy at the dealership called it?

Thanks guys!

That will cover it......before you order it print a copy and bring it over to a Mustang tuner let him know what your plans are. You never know, he may have a kit and could install it that same day. 3.73 & 4.10 Ford Racing Rear Gear kits are very common. Let us know how you like the new gears!! Good Luck!!

You don't specify if you have an auto or manual. If it's a manual, the handheld tuner can adjust the speedo setting.

IF it's an auto, you need to buy an aftermarket tune to adjust the shift points or depending if you take it to a mustang shop that can tune it for you when it's installed.

Sweet, thanks! Good idea, I'll print it out and make sure its what they're looking for.

I'm a MT guy - guess I left that out of my sig.

Perhaps not that common, but you might be better off just holding off on doing any purchasing ahead of time.

I´d suggest finding the shop you want first to do this before buying anything. The great place I took mine to (Swarr Auto)will just give the turn-around price including the FRPP needed. Installing second-hand parts, (even shown as new) at a shop is usually something they try to avoid for obvious reasons.

That is triple what it's worth. The gears are 200 tops,bearing and shim kit 80 and 60 and install is 300.

You can get pretty well everything from AM.

The kit you list there looks like it is from LateModelResto. I am going to be doing a gear swap on my 05 soon too. The oil in that kit is not the right weight. Check out AM....their website will tell you which oil to use....it is a heavier one.

You need 3 quarts like one of the previous posters mentioned. Your car is brand new or I would imagine not many miles....therefore you only need the basic install kit...about $36 from AM. So basically 3 things you need:

1. FRPP 373 gears
2. Royal Purple oil 75W140 x 3 quarts (no need for friction modifier)
3. Basic install kit

Get AM to price match the gears from BuyFordRacing (I believe they currently have the best price at least on 410's, which is what I bought) and get a mustang forum code from AM and get 6% off the other two items (basic install kit and oil).

The dealership is taking you to the cleaners on that price.

Damn that's high! You can get new Moser Axles, Detroit Tru Trac, Gears and install for that price!

I used the Royal Purple oil but my installer still recommended friction modifier, even though the oil says it's not necessary. It was put in as an added safety measure but it depends on your installer.

Free shipping from AM and the 6% off was a great deal on the oil. I bought my 4.10 gear set and build kit from streetsideauto.com, they were on sale and had a 15% coupon at that time. Ended up getting brand new FRPP gear set relatively cheap.

Traction-Lok is just a Ford name for their limited-slip diff. If yours is a 2011 GT...then you already have a limited-slip. If you're going to be abusing your car a bit (mostly launching hard) then you may want to consider upgrading to a heavy-duty limited slip as this would be the time to do it if you're changing gears. There's a handful of good ones out there. I've had an Auburn HD in my 1983 GT for a decade and have had zero problems with it...and I'm not easy on it.

Hope this helps.
