      Performance Upgrade. If your running a heavily modified or forced induction SN95 Mustang, your stock axles might be too weak to take the additional punishment. But after installing a set of SR Performance 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 28 Spline Axles are specifically designed for use on 1994 to 1998 GT and SVT Cobra Mustangs with or without ABS that have 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.

        Bent Axle

        Right rear axle was slightly bent, causing this unbearable squeak...after replacing them with the Sr Performance axles the squeak was gone. Hammering the studs in worked for me. Good product.

        Fit and worked like stock

        These were purchased to replace stock axles that were used-up from bad wheel bearings. The cost wasn't much more than stock units and the quality is better making the decision a no-brainer.

        4 1997 GT - JorgeR Installation Time: Afternoon

        Great quality axles

        The axles are a total upgrade from the stock ones - due to better steel. The backlash at the wheels was greatly reduced form the old ones, which had over 160k miles, and showed it's wear at the splines. I kept my original studs since they looked good and are better steel quality than the ones included in the kit.

        Solid Product

        Shipping was fast and the axles arrived with about 8 other boxes undamaged. The axles are solid quality. The only issue you may run into is swapping the exciter ring for the ABS system. Be prepared to replace that as well as the ABS magnets in the event yours don't come out in ome piece.

      I upgraded from 28 spline to 31 spline axels and 31 spline carrier. The axel bearings won't go on the 31 spline 5 lug axels, or do I have to clean the black oxide off the axels. Or are the Bearings different for an 8.8 rear end.

      • The diameter of the axles do not change between the 28 and 31 spline. The bearings should fit both a 28 and 31 spline. You can get in contact with one of our Mustang Experts by following the link below. This way we can ensure you have a proper install.

      I'm in the process of building ah overhauled 5.0 for my 96 SN95. After completion the garage that is creating a twin turbo kit for estimates 800 hp and so I am looking to upgrade the axle in my car. The question I have is how much can these axle rods take in terms of WHP?

      • Hi, These SR Performance 8.8 Axles - 28 Spline 5 Lug will only hold around 300 whp i suggest swapping to a 31 spline rear end and talking to a shop who can make you a set of custom axles for your application.
