This pair of SR Performance 5-Lug 31 Spline Axles are specifically designed for use on 1979 to 1993 5.0L V8 Mustangs that have upgraded to 5 lug wheels and a 8.8" 31-spline LSD or Spool only.
If your running a heavily modified or forced induction Foxbody 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.
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.
