Does the 4.10 gear come with everything?

[Motorhead350]

I have the Ford Racing gear and haven't installed it yet. Some shops were asking me if I had some certian parts (sorry can't remember what) and I thought the kit was complete. They were mentioning if these parts can be used again. I know this is a real shot in the dark, but does anyone know what I'm talking about or if the kit is complete? Thanks

You'll need a retune for the speedo and shift programming.

You may also need other things, pinion bearing, seals, axle bearings if they don't look good, rear cover gasket, fluid, etc.

Others can chime in with a list of optional stuff that is good to do.

But really, a good shop that knows what they're doing can take the gears and provide the rest.

Besides the gears you'll need:

Fluid, I used Redline.
Friction Modifier (if your fluid doesn't contain it, Redline already has it)
Pinion seal
Pinion bearing
Cover gasket

The gears should have come with the crush collar, if not you'll need one. I believe the FRP gears also come with a new pinion nut. Since both rear axels need to be pulled it's a good time to check the bearings and axels, especially if you have an '03 MM and the rear axel TSB hasn't been applied. You might also want to add the Ford Racing stud kit (less than &30) and a stud girdle.

Thanks. I got the speedo taken care of sense I have the microtuner.

Don't forget a shim kit.
The earlier gear kits came with them, don't know about the later ones.:)

The Ford Racing gears came with the ring, pinion, crush collar and shims.
I had to pick up a new pinion seal, friction modifier, and oil.

I had the 1725 microtuner after my 4.10 install and it helped the speedometer but the tranny still shifted way too quickly. Your going to have to play with the shift points to get it where you want it.

No!, You still have to provide the smile.

[Motorhead350]

Haha I'll smile when it's installed. I have had the gear close to a gear now and can't find anyone who will do it in one day. Plus I've had a range from 220-500 to install the thing.

does this extra gear imply 'studs and girdles'? I always hear those accompanying the gear upgrades. what are those?

[GreekGod]

The crush spacer for pinion bearing preload is not a good idea. I recommend using the Ford Racing solid spacer kit. It is not only better for "heavy duty" applications but it also allows future seal replacement without using a new crush spacer or having to check bearing pre-load.

this isn't an "extra" gear, but a new ring & pinion gear set that's of a different ratio than the 3.55:1 factory ring & pinion gear ratio that our Marauders came with in the rear end, which replaces the stock gears rather than being added to them. The 4.10:1 gear ratio will provide some better acceleration from 0-60 MPH than the factory 3.55 ratio does, and therefore better quartermile ET's also (although don't expect a night and day difference from a gear change alone in a car that weighs a whopping 4,200 LBS).

There are aftermarket support covers that are made of thick aluminum which is stronger than the flimsy factory stock stamped steel rear end covers and offers more support to the rear end housing which will prevent flex and deflection under torque and acceleration. They come with threaded studs and jam nuts that butt up against the differential bearing caps to futher support them.

Personally, I don't think that the cover and "stud girldes" are neccessary for a car that's producing anything less than 500 HP at the crankshaft. The Ford 8.8 rear end that's in our Marauders isn't the strongest rear around by any stretch of the imagination, but they aren't that weak either, and can take a fair share of abuse in their factory stock form. In fact, I never even installed a support cover equipped with a stud girdle on my Marauder, despite the fact that I have 4.56 gears in it along with a Roots Trilogy S/Cer, which churns out 400 HP to the wheels, and probably about 475-480 at the crankshaft, and the car has 48,000 very hard miles on it so far,(with 37,000 of them being S/Ced) and has also been raced at the dragstrip occassionally. But hey, to each his own, and I hope that I've answered your questions thoroughly.

yeah i was serious. just ran a search and it's mentioned. thanks for explaination

We can install in one day no problemo.
The only varible is the stripped hardware.
Just start early, allow some extra time to tap out the hardware .

If you are going to an outside shop and you don't know what fluids you should get, give RoyLPita a PM! He helped me get mine done through a friend of his and he told me exactly which scale fluids I needed and even the right pinion bearing. The bearing is a $15 item and the fluids are about $60-$70. I suggest you should get the T/A Performance cover with stud and bearing kit from Wes too if you're going to get 4.10s and just throw out the old cover. It maybe an extra $160 or so but it's worth it and the cap is a lot stronger than stock. Though a stock rear cover is fine if all you are doing is 4.10s and are keeping it n/a. I still bought the cover anyway just for the sake of getting it. Plus the cover has a drain plug which is makes future changing of the rear diff. fluids all that much easier.
