    Features & Details

    • 1541H Alloy Steel
    • 28 Spline
    • 5 X 4.5" - Five Lug Design
    • 10 Year Warranty!
    • Driver and Passenger Side Axles Included
    • Fits 1979-1993 5.0L Mustangs with 8.8" Rears and 5 Lug Wheels
    Performance Upgrade. If your Mustang is heavily modded or running a forced induction setup, your stock 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 1979 to 1993 5.0L V8 Mustangs that have upgraded to 5 lug wheels with the stock 8.8" 28-spline LSD installed.

    Application Note: 1979-2004 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.

        4 Top Rated Questions

        Will these axles work with a cobra brake kit on a Foxbody?

        • These Alloy USA 8.8 Axles will work with a Cobra brake kit in a Foxbody Mustang, as long as the stock Foxbody axle housing is used. If an SN95 axle housing is used, these axles will be too short

        Is the register bore for a stock 79-93 brake setup or sn95?

        • The Alloy USA 8.8 Axles will have a hub flange designed to accept wheels with a 70.6mm hub bore.

        Are these the same length as fox body original axles?

        • Yes, the Alloy USA 8.8 Axles are going to be the same length as the original axles just 5 lug.

        What are the hole sizes? I would like to put ARP studs in these, but the ARP knurl is .625, so will they fit or do I need to drill/reamer them? I noticed that the Moser axles require you to put a .625 knurl size stud in (same size as the ARP).

        • Hi, These Alloy USA 8.8 Axles - 28 Spline 5 Lug are designed to use studs with a .614" knurl,i do not suggest resizing the stud holes.

            Nice Quality and fitment

            These axles fit perfectly and made it easy to swap to 5 lug. Installation is the same as any other axle and you should have some knowledge of how to take the rear apart before starting.

            8.8 Axle review

            This came in a box bubble wrapped. It was hard to get to the parts but they were in perfect condition. All of the lugs pressed in well. I installed both of them in my axle and do not have any leaks or noise after putting 20k miles on them already.
