      Description

      Performance Upgrade. If your running a heavily modified or forced induction Foxbody Mustang, your factory 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 4-Lug 28 Spline Axles are specifically designed for use on 1979 to 1993 5.0L V8 Mustangs that have the factory 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.

        Best bang for the buck!

        Super easy to install and perfect fit. A good slide hammer and seal driver makes changing the axle bearings a breeze.

        1 1987 LX - KB Installation Time: Afternoon

        Snapped first time out

        After several years of hard launches my stock axle finally gave way and failed. I installed these axles with the hopes that they will handle the extra power of my modifed 87 Mustang coupe. Well I did a burnout with 26 x 10.5 E.T. Streets bias ply tires out back and when I left, the left axle snapped on the launch. I went with Mosers the next time and I should have went with them in the first place like my mechanic suggested. I would only suggest these as a stock replacement but nothing performance oriented that include hard launches.

        Ok

        I haven't installed the axles yet but they appear to be good quality. Good deal since the package comes with bearings, seals but my package did not contain all of the studs. I only received 5 of 8
