    Performance Upgrade. If your running a heavily modified or forced induction New Edge 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 1999 to 2004 GT, Bullitt and Mach 1 Mustangs that have 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.

      Gets the job done!

      Had a bent stock axle and bought this set. Worked out perfect, transferred the ABS rings from the stock axles and was done. Perfect for a stock replacement! Also ordered the bearing and seals while I was in there. Also from AM! Shipment was quick from AM!! Love these guys/gals!

      Upgraded Axle

      I had the original axles on my 2000 Mustang GT since 2001. One day I had noticed a spot on my driveway near the rear of the car. The leak was coming from my rear seals. It was time to replace the rear axles, bearings and seals. After the install no more leaks and now I have a piece of mind about the rear end of my Mustang. Shipping was fast (3 days).
