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

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

Josh

  • 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.

DarkAffinity

  • 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

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!

KrazyPony

  • 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!

    Installation was a breeze

    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.

    probably the most complete kit you can buy when doing a gear swap. All you need are the gears, fluids, and a speedo gear, depending on what year your car is

    Best mod I've done - 4.10 gears

    I've put more than $6k in mods in my Mustang, and this is by far one of the best ones if not THE best one. I've had my Mustang for 6 years and it never felt so alive. Acceleration and throtlle response are superb. I have not taken it to the track yet, but I'm sure its gonna drop at least 0.5 seconds. MPG actually got better in city driving and not that bad on the highway, just lost about 1 - 2 MPG, but gained 2 - 3 in the city. Top end speed is way over 120 MPH, no worries about that. Doing about 3000RPM at 85 MPH.

    3.73 gears for 8.8 axle

    The price on these genuine Ford Racing gears, and installation accessories were the best on the internet. Combined with a Ford Racing Trac-Loc differential I already owned, this made a great combination and really woke the car up.

    Cant go wrong with the product, fits perfect with out any issues.

    i just recently changed my gears last year (6k ago! ).my car puts down down some decent HP 565rwhp. I brioke my rear end at the track (ripped the spider gears and busted an axle) everything from the ring and pinion to the bearings looked awesome! nothing wrong with any of these items. the only reason iam replacing everything is cause i dont want take any chances.This is a great replacement option, drives like stock but performs really well.

    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
