    Features & Details

    • 1541H Alloy Steel
    • 28 Spline
    • 5 X 4.5" - Five Lug Design

    Performance Upgrade. If your Mustang is heavily modded or running a forced induction setup, your factory axles might be too weak to take the heat. These premium quality 1541H alloy steel axles will ensure that all the power and torque is transferred straight to the pavement - where it belongs.

    Stronger than OEM. Manufactured from high quality 1541H alloy steel using a computer controlled induction heat treatment that results in a stronger, more durable axle shaft. Alloy USA uses a cold-formed rolled spline process that produces an axle spline that is up to 35% stronger than standard cut splines.

    10 Year Warranty. These Alloy USA axles come with a 10 year limited warranty to be free of defects in material and workmanship from the date of purchase. Some limitations do apply. Please see the full Alloy USA Warranty disclosure for details.

    Application. This pair of Alloy USA 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: 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.

        do these axles come with abs tone rings on them? or do i have to transfer the stock ones onto these ?

        • The Alloy USA 8.8 Axles will not come with ABS tone rings, but will accept your stock ABS tone rings.

            Good product, looks to have being built with pride.

            Nice anodized black finish, to bad nobody will see them. If your car is equipped with ABS the tone wheel will be required to be transferred, no instructions are given as to how to either remove the tone wheel from your existing axles and to install them on the new axles. I heated the tone wheels with a heat gun and install the clam shell puller between the tone wheel and axle, then used long treaded bolts through the puller pushing on the axle, this pushes the puller up against the tone wheel and pushes the tone wheel off the axle. To install, heat the tone wheels again, and press all the way onto the axles.

            Just what I needed

            My mustang is a 99 and its got a few miles on it. when i purchased it i knew that it had taken a lot of abuse in the past. low and behold, my axles turned out to be pretty bent. so i found these little jems for an awesome price on AM. they did the trick, and now my car feels like it hooks better on take off. so far so good! thanks AM. OH, one speed bump i ran into was the ABS sensor rings. couldnt find new ones ANYWHERE, seeing how my old ones cracked when being taken of the old axles. but i eventually found them.
