    Features & Details

    • 8.8" Gear Installation Kit
    • Ideal for Rebuilds or Gear Swaps
    • Essential for 60,000+ Mile Ponys
    • Compatible with Both IRS and Solid Rear Axles
    • Fits 1986-2014 V8 and 2011-2014 V6 - Excludes 2013-2014 Boss and GT500
    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 pinion and carrier shims, crush sleeve, pinion seal, pinion nut, ring gear bolts, Shelby GT500 high-torque pinion bearing, heavy duty carrier bearings, cover gasket and all the required hardware.

    Attention 2010 and newer Mustang Owners. Starting in 2010 Ford changed the inner rear gear pinion bearing in all 8.8" equipped Mustangs. This kit includes the required 2012 Shelby GT500 High-torque pinion bearing.

    Application. This Ford Racing Ring and Pinion Installation Kit is designed for use with 8.8in rear axle equipped Mustangs, including the 1986-2014 V8 and 2011-2014 V6 models. Works with both Independent Rear Suspension (IRS) and solid rear axles.

    Technical Note: Does not fit the 2013 Boss or 2013-2014 Shelby GT500 Mustangs with axle codes S-215-D and S-219-D.

    Fitment: 1986 1987 1988 1989 1990 1991 1992 1993 1994 1995 1996 1997 1998 1999 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 2013 2014 Details

    Would this kit fit on a 15-17 v6? If not, do you guys offer a kit for the s550's?

    • Unfortunately, this kit will not work on 15-17 Mustangs. We do have a selection of gears for the S550s, you can find them here: https://www.americanmuscle.com/2015-mustang-gears.html#shop-by2

    What is the difference between this kit and the motive install and bearing kit?

    • The difference between the Ford Performance Ring & Pinion Installation Kit and Motive Rear End Installation Kit would be the high torque bearing. The Motive Rear End Installation Kit will come with the bearings and seals that you would need to change the rear end for your car. But, if you have a higher performance vehicle it is recommended to go with Ford Performance Ring & Pinion Installation Kit.

    I have a 2014 GT with track pack - 3.73 Torsen diff and it is developing the dreaded "whine". Will this kit (and specifically the high torque bearing) fit my Torsen differential 8.8 rear end? Scott

    • The Ford Performance Ring & Pinion Installation Kit with The High Torque Bearing will fit your factory Torsen Diff with no issues.

    The description for this kit states that this is a "complete kit", and also "Attention 2010 and newer... This kit includes the required 2012 Shelby GT500 High-torque pinion bearing." Which means that it does include the correct pinion bearing for, say, a 2012 V6. At the same time the site suggests to "Add 2010 8.8in Rear Gear Pinion Bearing" for additional price. Q: does or does not the kit have the correct rear pinion bearing included?

    • The Ford Performance Ring & Pinion Installation Kit w/ High Torque Bearing does indeed come with everything needed. The Ford Rear Gear Pinion Bearing would be helpful for your 12 GT500 as an additional upgrade to keep your rear end even stronger.

      Everything you need.

      It’s all in one package. No scrambling to find the parts for the rebuild. This is one area where you don’t want to go budget minded and figure you can save a dollar by trying to get the few pieces you think you may need. This kit is perfect.

      This kit was perfect! Didn't have to hunt down all the parts separately. Came with everything you need to upgrade your rear end gears. I went with Ford Racing 4.10 over the under performing stock gears.

      Great Quality, best price!

      Great quality, best price and easy installation. Just make sure your pinion pre load is set correctly, otherwise you will need to disassemble the whole thing again and may ruin your bearing. The biggest challenge was to get the backslash set as I changed the differential as well.

      Alot better quality than the other kits, especially the bearings and the ring gear bolts. I would only suggest ford performance bolts. the motive ones are micky mouse compared to these.

      Ball bearing destrcution

      I have bought this Ford Racing Kit to prevent problem with not oem bearings. I've followed all advices about the good way to install this stuff, checked all tightning's torques, and realized this operation with help of a mechanic specializing with american cars. The car has started to make a noise like a tire that rubs only when accelerating and turning on the right. After 3 checks nothing was found. So i decided to use the car to see evolution of this problem... 70 kilometers later, back to my home after work, the front's bearing pignon has exploded. My mechanic a succeed to find quickly a new bearing (Timken) in France to fix it. Despite this problem, and the distance, American muscle has made a commercial refunding to me : great an professionnal service.

      Perfect install kit!

      This kit worked well. I was impressed with it;s quality. I had used Yukon kits in the past and this Ford Racing kit was superb. I do get very precise when setting up a differential. I do use a dial indicator and sometimes it's necessary to press off the pinion bearing and re-shim and this bearing did not deflect or distort when being pressed back off. This is a nice install kit.
