Performance Upgrade. 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.

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 1979 to 1993 5.0L V8 Mustangs that have upgraded to 5 lug wheels and 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.

Fitment: 1979 1980 1981 1982 1983 1984 1985 1986 1987 1988 1989 1990 1991 1992 1993 Details

    Great axles for a great price!

    Great axles for anyone upgrading to 31 spline. Bought one set and fixing to order another set for a different car. Add these with the Ford 31 spline Trac loc for a bulletproof 8.8!
