    Performance Upgrade. If your running a heavily modified or forced induction Foxbody Mustang, your factory axles might be too weak to take the additional punishment. But after installing a set of SR Performance 1541H alloy steel axles you will be sure to get all your pony's power and torque firmly planted to the pavement - where it belongs.

    Built to Out Perform. SR Performance Axles are forged from premium quality 1541H high manganese steel alloy that is induction heat treated for an axle shaft that is stronger and much more durable than stock, making it perfect for high stress street and race applications.

    Application. This pair of SR Performance 5-Lug 28 Spline Axles are specifically designed for use on 1979 to 1993 5.0L V8 Mustangs that have upgraded to 5 lug wheels with the factory 8.8" 28-spline LSD installed.

    Application Note: 1979-2004 V8 Mustangs came factory equipped with 28 spline axles, except for 2003-2004 SVT Cobras which were 31 spline.

        2 Top Rated Questions

        I have a 93 cobra rear end with disc brakes. Can I just drop in these axles and purchase aftermarket 5 lug rotors (10.25”) designed for fox? Also, will the hub size on the these axles create problems with fitting stock foxbody wheels ( ponies) or finding aftermarket wheels?

        Will I you able to use rear disk brakes off a 94-95 mustang?

        • It is possible to use rear disk brakes off of a 94-95 mustang, however, modification would be needed and the addition of several parts to install a rear caliper and disk setup onto the fox body mustangs.

            5 lug conversion

            Got these to the door the next day of ordering. Easy to install but a long way to complete the restore.

            SR Performance 8.8 Axles - 28 Spline 5 Lug (79-93 5.0L)

            These axle shafts seem to be of great quality no modifications were needed great fit. The new bearings and seals included are a big plus so you can reduce the chance of failure anytime soon. The new wheel studs included took a little work to get installed but very doable in the home garage none the less. I would highly recommend these for the 5 lug conversion or 5 lug replacement. There is no sense in buying stock salvage yard axles that are potentially damaged when you can buy these at such an affordable price.

            SR Performance Axles

            These axles are a great improvement over the stock axles in my mustang! I would highly recommend them to anyone looking to improve their rear end's strength! Very affordable as well. Keep up the great work AmericanMuscle!
