Performance Upgrade. If your running a heavily modified or forced induction S197 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 5-Lug 31 Spline Axles are specifically designed for use on 2005-2014 GT, Bullitt, BOSS, 2011-2014 V6 as well as 2007-2009 Shelby GT500 Mustangs that have the factory 8.8" 31-spline LSD installed. ABS rings are not included.

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.

    great product as always from AM

    Axles where shipped in great packaging, I read other reviews and they all said get some studs or re use old ones. Because the ones in the kit were to small, they were so I picked some up from my ford dealership. But I have had the axles in for about 3 weeks and everyhting is working perfect.

    Good product but...

    I had these axels installed when I had my rear end rebuilt. My mechanic said it all went together good. However the wheel studs are way to short and he could only get the lug nuts on about 2 threads which is huge safety concern.

    Bent Axle fixed

    I had a slightly bent axle on LH side which caused a slight squeaking from the LH brake. I ordered SR 8.8 axles-31 spline are solid and fit great. I Used original Studs and the ABS rings transferred easily. Exact fit .1mo, so far so good.

    Great product

    Product fit very well trick to remove abs wheel heat with torch and pry off. To install abs rings clean them then put them on a stove for a couple of minutes grab with pliers and they slid right on the axle!

    OEM Quallity

    Fairly easy to install if mechanically inclined with the right tools, everything went well with the install. Wish the ABS rings came with but was not hard to re-press them onto the new ones (RE-Press Meaning a Hammer and a block). The only thing I ran into was the replacement lug nut studs that came with the product, they were to short for the application maybe shipping error or just the standard requirements into shipping. but that being said I just tapped out the old studs and re-installed them into the new shafts and everything seems to be just fine.

    Great axles but needs some parts.

    The axles were great and a perfect fit. Only complaint was the studs were shorter than factory so I couldn't use them and it doesn't come with the abs tone rings.

    Good product

    Instillation wasn't to bad, everything fit and went together perfectly. I haven't noticed anything along the line of performance, just had to fix a broken axle.

    I would highly recommend

    The only flaw with this product is not coming with an abs ring, but if you heat the old one up and lightly tap it you can get it off without breaking it and use it on the new axles

    Vroom!

    Loved them! Bent one of my axles and put them in replacement of my old axle shafts. The difference noted in pulling is beyond extreme!
