    Review & Installation Video

    Review & Install Video

    Hey guys, I'm Alex from americanmuscle.com, and today I'm bringing you my quick review and breakdown of the SR Performance 31 Spline 5 Lug Axles, fitting the '05 through '14 GT, '11 though '14 V6, and '07 through '09 GT500. So in this video, I'm gonna give a quick overview on who these axles are going to appeal to, the construction and materials utilized here, the price, and then what it's gonna take to get these onto your Mustang, where I'm gonna be giving these a pretty involved three outta three wrenches on the difficulty meter and a three to four hour job. So the SR Performance axles that I have here today are going to be a great option for any GT, V6, or GT500 owner that's either in need of a replacement axle or for someone that's just looking to get into a tougher setup. These axles are gonna be great for the Mustang owner that's using their car as a daily driver or a weekend warrior, in comparison to a car that's gonna be seeing track time every weekend, as these aren't gonna be manufactured with the same tolerances as another set out there like something from Moser or Strange. In terms of the construction and materials here, we're gonna see these are going to be manufactured out of an OE type material, which is gonna be 1541H high manganese steel, which is typical of what you're gonna find from most, if not all aftermarket axles. Now in terms of the pricing here, you should expect to be spending 300 bucks for this kit. In comparison to some of the other options out there, you're gonna see that they can easily go for upwards of about a thousand dollars, but that's gonna be based on their intentions and what they're gonna be used for, and I just wanted to give you an idea of what else is out there. Switching gears to the installation portion of the video, like I said up top, this is gonna be a three outta three wrenches on the difficulty meter. It's definitely not something for the faint of heart. However, if you have done this kinda work before or if you opened up your rear end previously, I don't think you're gonna have that much trouble, but this is something that I honestly wouldn't leave to a novice wrencher out there. Now I will say this up top that this is gonna be a brief overview or glance at what's gonna be entailed to get these onto your car. A couple steps might be missing here, but you're gonna have a wealth of information in order to help you get these installed on your car if you choose to tackle this in your garage. Now looking ahead, some things I'd make sure to have on hand here are gonna be a full socket set, a couple jack stands, a few oil pans, and then some fresh oil for when you're gonna be cracking that diff open. Now to start, I'd suggest loosening the lug nuts on your car before you get it up in the air. Once it's on the stands, take everything off and then remove your caliper, caliper brake, rotor, and dust shield. So once that's done, you're gonna wanna get underneath the car and locate the pumpkin or the diff where you're gonna wanna position a fresh pan underneath, locate the fill plug, and then begin taking the differential cover off. So after that's cracked, that's when the fun part starts coming in. You're gonna need to locate the lock bolt inside of the housing which will need to be removed, then you'll pull the pinion shaft along with the C-clips, and you're damn near done pulling the OE set. After this, assuming you do have new ABS rings, they're gonna need to be pressed on, and if you don't have the equipment to do this in-house, I might suggest having a shop do this just to be on the safe side. After that, it's merely gonna be throwing everything back together and buttoning the car back up. Again, you're gonna be looking at a pretty solid three outta three wrenches on the difficulty meter here and about a three plus hour job. All right, so just to wrap things up here, some final thoughts, if you're the Mustang owner that's in need of a quick fix for a broken axle or if you're just looking for something a little bit more tough than your standard setup, I would definitely recommend checking these out for your Mustang. So I'm Alex from AmericanMuscle, and that's my quick review and breakdown of the SR Performance 31 Spline 5 Lug Axles, fitting the '05 through '14 GT, '11 though '14 V6, and '07 through '09 GT500, available right here at americanmuscle.com.

    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.

    Does this fit on the drivers side . The back rim ? Is it for all ? The front and back ?

    • These SR Performance 8.8 Axles would go on the passenger and driver sides of the rear axle.

      Quality axle, good for nothing wheel studs.

      I was impressed with the quality of the axles. But when I went to install the wheels, I noticed the studs that came with the axles only allowed the lug nut to grab about 2 threads. There was no way I was going to drive like that, so I installed the factory studs that were significantly longer.

      Wheel fell off

      Easy install I should of read the reviews before studs are shorter then stock had a hard time putting the lugs in when I finally did took the car for a drive around the block wheel fell off before making my first turn no one in town has stock studs so car is down. I don't understand the point of shorter studs.

      Good axles

      So I ended up having to buy new ford speed sensors. No problem. Axles and additional parts all fit and work well. But makes a loud drone noise at first. I guess I need an alignment and to break them in.

      Real Nice Set

      I bought this after a lot of shopping and found it was about the best value point. Just be aware, the studs included are not long enough to use anything besides stock rims. We had to switch studs with the shafts installed which is a trick in itself. The fit was perfect and the construction of the shafts is sturdy.

      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.
