      Performance Upgrade. If your running a heavily modified or forced induction SN95 Mustang, your stock 28-spline axles might be too weak to take the additional punishment. But after installing a set of SR Performance 31-spline 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 31 Spline Axles are specifically designed for use on 1994 to 1998 GT and SVT Cobra Mustangs with or without ABS that have upgraded to a 8.8" 31-spline LSD or Spool only.

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

        Do not order!

        Huge let down! Received axles that were almost an inch shorter than described! Do not order these! Quality control sucks! They do not fit a 95 cobra!

        1 1995 GT - DanielR Installation Time: Shop Install Installation Cost: $500-$1000

        Terrible purchase

        This was a terrible decision to go with these axles, they are .75 inches too short and will not allow room for the abs gear nor is the shaft big enough to even alow the gear to be pressed on. Being the shaft is too short now the brake system is out of alighnment to work. So I had to buy spacers to fit the rotors and calipers to fit in spec... and now the studs are too short to fit the wheels. And it just keeps going on and on. TERRIBLE IDEA!!!!
