Description
Performance Upgrade. If you're putting down lots of power and torque in your GT, Bullitt, or Mach 1, a pair of Moser Engineering 31 spline axles is a high performance upgrade that will help you put that tire-smoking power to the ground.

Street and Strip. If you have a heavily modded street or strip Pony, your stock 28 spline axles might be too weak to take the heat. These premium quality forged steel axles have 31 splines to ensure all your power and torque are transferred 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!

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

  • Yes. Plus you can order them with the c-clip elims. already pressed on, plus any thing else like reluctor rings for ABS/ Traction Control to stay working if you want.

  • The old rings will work just fine, but depending on the cost you might just wanna replace them anyways. When doing any type of work you should replace any small parts , gaskets, and seals that are inexpensive to increase overall life of that part or system.

  • There is not much of a difference in weights. I would want to say the aftermarkets are worth the extra security though vs. a few extra lbs. they feel the same to me though.

    Satisfied

    I run these in my GT and very content with the performance of the axles. They are very durable and can pretty much take any rpm you throw at them. Not to mention the pretty reasonable price. Ive been running them on slicks for about a year and have no problems at all.

    Excellent Product

    Just installed these along with a FRPP 31 spline differential and couldnt be happier. Great upgrade for any car that sees the track from time to time or even for a track only car. These Moser axles can handle quite a bit of abuse.

    the way to go.

    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.

    Moser 31 sline axles

    Had these installed the other day along with 4:10 gears and 31 splne differential in my 2003 Mach 1. So now it is time for some sticky tires and let her RIP! Great AXLES!!!

    Moser 31s 04GT

    I got these when I had my gears changed out. I took the high torque differential carrier out of my dads 08 GT500 when he crashed it. I needed the 31spline axles to use it. Used it with 3.73s. Great piece and went smoothly. (we sold the GT500 and bought an 09 and built it up to 650RWHP by the way)

    Fit like a glove with the new diff

    These are a great "insurance" when adding more power to your mustang. I shouldn't have to worry about breaking a axle anytime soon!
