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.

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

      Using this for a Factory Five 33 Hot Rod build, and was wondering if there was any kind of seals I would need to get along with these?

      • The Moser 8.8 Axles will come with the axles only, so new axle seals would be required. We do offer axle seals under part number 50261.

          Moser 31 spline axles

          I do not have my Mustang running yet since this is a major upgrade project. My Moser axles arrived promptly and were well machined, complete with studs, and easily installed.

          4 LUG TO 5 LUGS AXLE SWAP

          I used Moser 5 lug axles 31 spline from a 1994-1998 for my 93 Coupe/Notchback along with a 31 spline differential. Now I can run all the 1994-2004 Mustang rims/wheels which gives one the largest selection of wheels. No other mods were required for the rear. The 28 spline stock axle are just weak and will not hold up to extreme torque of the 4:10 gears ratio. I am glad I made the switch and down have to worry about breaking and axle and damaging the quarter panel and axle housing. Thanks American Muscel!!!

          Nice price!

          My 28 spine carrier spides were worn out and a new 31 spline was only $60 more than new spiders. It did mean mew axles were in order and AM had a great price on Moser, $239. Still in the middle of rebuildkng the axle. But the the Moser peices look good and it was nice to be able to upgrade/replace at a better price than new 28s!

          I put these on with a new Ford performance differential and the ride felt smoother than before. Rear end is all new so it feels nice.

          Super Beefy

          Finally decided to upgrade my stock, weak 7.5 rear end for a 8.8 assembly. In comparison to the factory axle, this thing is big and beefier. I got the 31 splines as well. I know this thing will handle the abuse I'm bound to give for years to come. One thing to note, mine DID come WITH studs pre installed. Even better!

          Well made and much more durable than OEM. Perfect fit and easy installation with zero hang ups. Worth the extra money and better warranty vs other options. ABS reluctor rings went on with ease also.

          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.

          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.

          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!

          you cant beat the quality, and its so much stronger then the factory 28 spline why wouldn't you want to go with the 31 spline.

          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.

          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.

          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.

          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

          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.
