Perfect for Installs or Rebuilds. When installing new gears in your Pony it only makes sense to replace the old worn seals and bearings while the housing is apart, especially if it has over 60,000 miles on the odometer. A Ford Racing Ring and Pinion Installation Kit is extra insurance against the need for another costly tear down and rebuild.

Complete Kit. This Ford Racing kit comes complete with all the components needed to swap out your ring and pinion gear. It includes gaskets, seals, shims, bearings and all the required hardware.

Application. This Ford Racing Ring and Pinion Installation Kit is designed for use with 8.8in solid rear axle equipped V8 Mustangs, including the GT, Bullitt, Mach 1 and the 1994-1998 SVT Cobra. It will not fit the 1999-2004 IRS equipped Cobra.

Fitment: 1986 1987 1988 1989 1990 1991 1992 1993 1994 1995 1996 1997 1998 1999 2000 2001 2002 2003 2004 Details

KevinD92....Ford doesn't make bearings. So, what brand of bearings come with this kit?

Will this kit fit on a 96 Explorer 8.8 rear end?

The Ford Performance Ring & Pinion Installation Kit is designed to work with 86-04 Mustang GT models only and will not work with a 96 Explorer.

Hello i was curious as to what kind of bearings you are using in this kit? Koyo or timken?

For this kit, Ford uses its own bearings.

Is this all I would need for my 8.8" rebuild? My 1996 Mustang GT has over 200k miles and started leaking out of the right rear axle seal. Does this kit include everything I would need to completely rebuild my rear end? Other than fluids that is.

Just to reseal the rear end and replace bearing yes its all you need but to completely rebuild you would need to replace your traction loc discs if you have a limited slip rear end
you might want to consider also replacing the actual carier and get a ford racing traction lock carrier for 250 since the disks in the original are probably toast. but yes this kit will stop your leak as it does come with axle bearings, to remove the original bearings you will need a slide hammer you can order from summit.

Replacing Rear Gears and Bearings Hello, I'm needing to replace my rear axle bearings as I was informed from a mechanic last night since he said mine are about shot, and figured if I'm going to do that I may as well replace the rear gear and pinion while in there since I;m at about 157k miles and growing daily as its my road warrior for my daily commute. I can get a slightly used FRPP 3.73 with only 5k on the gear in good condition fairly cheap from a friend. And wanted to make sure this is all I need to replace the rear end for the installation bearings and axle bearings, ect. I didnt see any Purple Power Fluids mentioned here, can you recommend anything else I need for the installation or links to them on your site? Thanks!

To complete your install, you will want this FR Installation Kit for sure. It comes with all the bearings and shims needed for a full replacement. Also, you will need new 75w90 gear oil and to recalibrate your speedometer to the new gear ratio. I've included links below for to the best way to recalibrate your speedometer, the SF3 Power Flash Tuner. You can get custom tunes through our Bama Team to correct your speedo and get the best performance from your Stang! The Royal Purple gear oil has a friction modifier included and is the perfect complement to new gears!
To do this install correctly u will need the ford racing ring & pinion installation kit 8.8 solid rear axle that will have all the parts needed , you will also need rear diff fluid synthitic blend ,you can use royal purple,castrol or mobile 1 rear diff fluid ,ford also recommends an additive to use with the rear diff lube this additive is used for the clutch plate thar are inside the rear diff,your local automotive store will have the correct fluids needed ,i use castrol syntec rear diff lube this has the additive already mixed in ...good luck on your install :-)
To do a ring and pinion and all the bearings its all you would need. Need to consider the limited slip discs too while you have it opened if you have tration loc rearend.

Do not buy without a 20 ton press on hand.

Took me a month to get all of this done just because I had to take time calling Ford and ordering more tools just to find out it can't be done the way they say it should. You need a 20 ton press to start the crush washer. Look it up yourself it you don't believe me.

Does what it's supposed to do

I mean, it's a rebuild kit. It's not really a performance piece. The parts fit, there's no bearing noise, and nothing seems like it's about to fall apart 200 miles later, so it's doing what it's supposed to. No leaks, etc. Had the install done at the same time as replacing the diff and ring/pinion, so all done at a shop

Always use Ford Performance

Used this kit when installing my Motive 3.90 gears. Guy at the shop was very happy I bought the For Performance install kit. He said I made a smart choice with it. I highly recommend you go with this kit when doing a gear swap.

This kit has everything you need to put in your new ring and pinion. I bought this kit with 3 jugs of gear oil and there was no need to interrupt the job to do a parts run. Highly recommend this to anyone.
