Description
Performance Upgrade. If your Mustang is heavily modded or running a forced induction setup, your stock factory 28 spline axles might be too weak to take the heat. These premium quality 1541 carbon steel axles have 31 splines to ensure all that power and torque is transferred straight to the pavement - where it belongs. Stronger than OEM. Manufactured from high quality 1541 carbon steel using a computer controlled induction heat treatment that results in a stronger, more durable axle shaft. This shaft also uses a cold-formed rolled spline process that produces an axle spline that is up to 35% stronger than standard cut splines.

Application. This pair of Superior 5-Lug 31 Spline Axles are specifically designed for use on 1999 to 2004 GT, Bullitt and Mach 1 Mustangs equipped with a 8.8" 31-spline LSD or Spool only. Application Note: 1986-2004 V8 Mustangs came factory equipped with 28 spline axles, except for 2003-2004 SVT Cobras which were 31 spline. All 2005 and newer V8 Mustangs come equipped with 31 spline axles.

  • Yes these will work fine. The better thing about thse are that there stronger than OEM so if you make more power later thay will hold up better. Make sure you have a 31 spline rear end.

    Superior axles

    September 21, 2012

    I installed these axles two weeks ago and I had no problems. I have made atleast 10 passes with them already and they are holding up much better than the old stock axles that I bent. I would highly recommended these for everyone.
