Performance Upgrade. If your SN-95 GT or Cobra is tearing up some asphalt with its power upgrades, your stock 28 spline axles might not be able to put all that power to the pavement. A pair of Moser Engineering 31 spline axles are the ideal upgrade to help you transfer all that torque straight to your tires.

Street and Strip. Whether your GT or Cobra stretches its legs on the street or the strip, Moser's axles are guaranteed to perform when the heat is on. These premium quality forged steel axles have 31 splines to ensure all your power and torque are put straight to the pavement - where it belongs.

Built to Perform. Moser Engineering 31 Spline Forged Steel axles are made with some of the toughest, strongest, most durable materials available. These axles feature machined C-Clip grooves to fit OEM application 8.8 inch rear ends. They are non-tapered and also feature hardened bearing seats for durability and performance under high stress conditions.

Customize. Moser Axles feature the ability to be shortened and resplined if you decide to narrow your rear at a later time.

ABS. Worried about deleting your factory ABS? Well now you don’t have to with Mosers quality design you can relocate your factory ABS sensors when installing your new Moser axels!

Application. This pair of Moser Engineering 31 Spline Axles are designed for the 1994-1998 GT and Cobra Mustangs. Wheel studs are not included.

Tech Note. For use with a 8.8" 31 spline LSD or spool.

  • Hello! The 31 Spline Moser 8.8 Axles have a center bore of 70.3mm


Do these axles come with the ABS rings.


Helpful (0)
  • The Moser 8.8 Axles - 31 Spline 5 Lug do not come with ABS Rings and new ones will need to be pressed onto the axles.


Can I use these on my 91 fox body, I know they are longer. But would they fit or is it better to get the shorter ones for the fox body years

  • These Moser 8.8 Axles are not designed to be used pre-1994 & post-1998, and they would cause some fitment discrepancies. We strongly recommend the Moser 8.8 Axles, Item number 73000, which are specifically engineered for your Fox, with the use of a LSD or spool.


Do I need to purchase any seals or bearings? I want to buy stronger axles for my cobra and i ran into these, but i noticed that the other axles come with bearings and seals and these are just the axles. Do i need to buy new bearings and seals or do the stock ones cut it?

  • I 're used my stock ones because they were still in good shape, although some new ones would definitely wouldn't hurt.


Automatic? I was curious if these axels would fit a 1996 GT automatic? I'm looking to add a posi. Thanks.

  • Yes. They are a direct fit into the rear end housing. You will need to upgrade the differential to a unit that is compatible with 31 spline axles, but you are already looking at that option. (totally worth it, btw) As long as you have it torn apart that far, just throw in a new gear set with the posi, get the rebuild kit for the rest of the rear end, and think about changing out the the bushings and control arms as well.

    I installed these on my 95 mustang so that I could use a Torsen differential that only accepted 31 spline axles. These axles are visibly beefier and a little heavier than the factory axles. They come with studs steady in them, which is great. I transferred the tone rings from the old ones to the new and they fit just fine. (Not that it was easy to transfer them, but it's the same process with any axle) Installation is just like a factory axle. Good product, I recommend it.

    Moser 31 Spline axles

    Love the way these axles fit my 97 Mustang Gt. They appear to be made of high quality steel and I really like the studs that came with them, already attached. I also bought the 31 spline Cobra trac-lock with carbon discs and it makes for a solid upgrade. Highly recommend.

    Great Axles

    Bought these as part of a complete rear-end rebuild on a 1995 GT. Great axles! No complaints at all. Much heavier duty than the stock ones.

    great product and price

    I bought these axles, and so far have been very happy with them. the install was easy, however, they will NOT work with ABS unless you remove the tone ring from your old axles, and press it onto the new ones. Other than that, replace all bearings while your at it too! Installed with an eaton limited slip, and together they work great.

    durable, strong, reassurance

    You can feel and see the strength in these axels, great improvement over stock 28 splines in my 97 gt, now I have no worries launching it nice and hard with complete confidence, recommend upgraded girdle, and if your going from a 28 spline your gonna need a new carrier, great time to upgrade to limited slip if you don't have it already

    7 months and already rusted!

    I ordered these in November '13 and got them professionally installed mid December. It is now July and the visible part of the axle is badly rusted. I live in California and have barely had any rain this year. Not sure what I can do about it but it's very frustrating.

    strong and reliable strip and street use

    The moser 31-spline axles I purchased for my 1998 Cobra are a great addition to my 4.10:1 and limited slip rear end setup. I have had problems with other brand axles and since replacing them with Moser axles, I have not had any issues since the install that I was easily able to do myself. A great priced and quality product for street and/or strip car. Thanks again for another great product for my Mustang.

    much better than the stock units

    Had these installed with rear end rebuild. These were installed along with frpp 3.73 gears, frpp tracloc, and the frpp install kit. The shop that installed them had to machine them down to get the ABS rings on. This is something they have had to do on other Mustangs. The old rings would not come off the old axels so new ones from Ford were purchased. The new set up is great. Totally satisfied and as always great service from American Muscle!
