Review & Install Video

Hey guys, Stephanie with, and this is my review of this SR Performance Bumpsteer Kit for the 2005 to 2014 S197 Mustang. This bump steer kit is going to be a good option for anyone that has a lowered S197 or is thinking about lowering. A bump steer kit is really for lowered cars because any time you lower your Mustang, you're essentially changing the geometry of your suspension. When you start playing around with geometry, you have to keep in mind that it could possibly create a bump steer problem, or basically an undesirable change in tow angle. This kit is designed to stop that bump steer and keep everything in line. So your stock components do not have any adjustability to them, and bump steer isn't necessarily an issue that can be foreseen 100% of the time with a lowered car. So I'd say it's unpredictable, which in turn makes handling and cornering unpredictable. But if we take a look at this kit that's designed to eliminate that problem, I see a few things that are worth mentioning here. The first thing I see here are spherical rod ends that also have tapered shafts. These are designed this way so you don't have to drill the spindle for the install. Another thing I'm noticing is a handful of bushing spacers that are going to help correct the angle that the tie rods meets the hub assembly which is going to change per car depending on the suspension set up. There are about 12 here, which happens to be the norm if we compare this kit to other options that are out there. So it's nice to see that even though SR is more of a budget friendly brand, they still give you a comparable product at the end of the day. Like most suspension mods, this kit does work best with other suspension mods like lowering springs and sway bars and caster camber plates. These are kinda like the final component to lock in the steering and handling, but even if you don't have a ton of suspension mods, and just have a set of springs, I'd still strongly suggest a bump steer kit, because the moment you put lowering springs on a car, you've created a need for this kit. And this happens because, like I touched upon earlier, when you lower a car, an angle is created where the tie rod meets the hub assembly. You don't want this angle, and the shims in an adjustable bump steer kit like this one here help to eliminate that angle. Now when we start to check out the cost, this kit costs in the price range of $100 to $200, being closer to that $100 mark. And like I just said, it is less expensive than other options that are currently on the site. When it comes to the install, guys, I don't say this too often, but I do recommend taking this to a shop unless you have prior experience in this area. You're going to have to get the car aligned after the install anyway, so you can just drop it off to get everything done in one shot. This is a three out of three wrenches on the scale, and if you do decide to do this at home, it's probably going to be a half day's worth of work. And I'm only saying that this is a difficult install because you do need some expertise to get this done. If the install and setup are done incorrectly, then you're just going to be making the bump steer worse. So if you're doing this yourself, you are going to need a handful of tools. A ratchet and an 18 mm, socket, a small and large adjustable. Some WD40 might help. A hammer or mallet and a tie rod end separator could be helpful too. You do want to make sure that you have a torque wrench to keep everything in spec, though, and you've gotta get to the wheel hub, so you'll need a jack and stands to get everything up so you can disassemble the outer tie rod from the wheel hub, and this is where you'll need your 18 millimeter. You can expect to see a nylon locking ring that you'll have to back off too, and you can use the mallet to knock the top of the bolt to separate the tie rod from the hub assembly. Then it's just a matter of removing the heavy nut keeping the outer tie rod end of the wheel hub assembly and unscrewing the outer tie rod from the inner one. Then you're going to want to compare the old tie rod to the new one, and make sure that the new assembly matches the length of the old assembly. And just tighten the jam nut on the steel end against the collar to lock everything into place. The spacers that are provided are to be used between the inner tie rod and the hub assembly, and the amount of spacers that go on the top versus the bottom depend on how much you've lowered your vehicle. After all of this is done, it's just a matter of reassembly and torquing down the two nuts towards each other. And don't forget, if you do this at home, while you can get your tow close to where it needs to be, you should still go for an alignment after the install. So if you're lowering your Mustang or you already have, this is a kit that you should really consider to keep your S197 suspension in check and functioning to the best of its abilities. This is a solid kit that offers a lot of adjustability, and as far as price, it's less expensive than the other options on the site. You can check this kit out more online and see what other customers are saying about it. I'm Stephanie, and for all things Mustang, keep it right here at

Improves Handling. Correct your Mustang's front end suspension geometry and eliminate bumpsteer with a SR Performance fully adjustable bumpsteer kit. Replace your stock, non-adjustable components and gain better, more predictable cornering and handling.

Adjustable. SR Performances fully adjustable kit provides a wider range of adjustment than other kits to allow you to fine-tune your suspension for improved steering response and crisp cornering.

No Drill Installation. Unlike other kits which require you to drill your spindle out during installation, SR Performance Bumpsteer kit features spherical rod-ends with tapered shafts for an easy installation with no drilling.

Application. This SR Performance Bumpsteer kit is designed for all 2005-2014 Mustangs, including the V6, GT, Bullitt, BOSS and Shelby GT500 models.

NOTE: Bumpsteer is a change in toe angle caused by the suspension moving up or down. Bump-steer is built into the geometry of the suspension and steering system, and has nothing to do with turning the steering wheel. The effect of bumpsteer is for the wheel to toe-in or toe-out when the suspension moves up or down. This toe change or "steering" occurs any time the suspension moves, whether it is from body roll, brake-dive, or hitting a bump in the road. Bump steer is undesirable because the suspension is steering the car instead of the driver. To fix a bumpsteer problem, you need to alter the height of the outer tie-rod relative to the steering rack with adjustable tie-rod ends, also known as a bumpsteer kit.

Is this the right kit for replacing my outer tie end rods? I need to replace inner & outer tie end rods. I already have the inner from you'all & was going to purchase outer tie end rod but saw the bumpsteer kit! Please let me know if I just need to purchase bumpsteer kit by itself or with outer tie end rods? Really don't know if I have a steering problem but just want to make sure I purchase correct parts because haven't replaced either tie end rod since I have had vehicle which I purchased in 2011! (2006 Ford Mustang GT)


  • This kit will work for the repalcement of your outer tierod ends. If your vehicle has been lowered you can use the included spacers when installing . If not then then just install them without. Your Alignment shop will be very happy with the quality of this product also.

    It really works like a charm

    Before my car would just turn by itself on bumps, which was very dangerious and i didn't know what to do so, after an intence research i found this bump steer kit and i thought let me give it a shot and i was stunned by the results. No my car handles like it should. And it only took about and 1hr tops for replacing both ends.

    Didn't fit

    So I recieved the package quite fast and it had everything in the box that it said it was suppose to. The install was quick and very simple but when I tried to put my stock rims back they would go on. I soon realised it was due to the fact that the bumpsteer kit was sticking out too far from the rotor and the inside of the rim was hitting it. I kept looking through the instructions and I had done everything correctly so I couldn't figure out why they weren't going on because on the site it says the bumpsteer kit was suppose to fit my year and model of mustang. I then went to the chat with an expert option and asked him what the problem was but all he did was say "you installed it wrong" and then sent me a link to the instructions I was already using. I then told him that it looks exactly like it does in the final picture on the instructions which is a picture of the final product and I said even in the picture it sticks down from the rotor quite a bit. He then replied with "no it doesn't you installed it wrong" and " I can't help you unless I'm there". So he wasn't much help to me. After that I put on a much larger set of 18 inch rims and the install was a breeze and the product works great. If you're using chat with an expert and the experts name is william just disconnect and try and find someone else.

    Awesome bang for the buck!!!

    I bought these when factory ones wore out. I had plans on lowering my Mustang so figured I buy for the future. After install I took a ride to get alignment and after notice how solid my steering felt as well as how wore out the stock ones were. Awesome product and thanks to American Muscle for great customer service and speedy delivery. You guys rock!

    Upgrade Your Suspension

    Got this done along with several other suspension mods so I can't objectively say how much this one particular part played a role but guys at the shop seemed impressed with them. These along with other suspension mods made my driving experience so much better. Never realized what an upgrade over stock suspension would do but it feels like an entirely new car. Much more responsive and no more plowing through turns. Full suspension upgrades included... 1. GT500 Strut mounts 2. Koni struts/shocks 3. SR front/rear sway bars 4. JM adjustable panhard bar 5. SR Bumpsteer 5. SR Rear Upper/Lower control arms 6. Ford Racing front control arms 7. Ford Racing Lowering Springs So for all practical purposes a new upgraded suspension. Bought everything gradually over the course of the winter and I recommend to anyone to do something similar. You won't be disappointed.

    Doesn't last

    I bought these along with several other suspension upgrades. After 1 year of light use (I put less than 5000 miles a year on my Mustang) these are already failing. I started having a vibration in my steering wheel and began hearing a squeaking noise coming from the wheel area. Took my car to the local shop and they confirmed it was these. This is the 2nd SR Performance product I've had fail within a year. From now on I'll stick to reputable brands. No item whatever price point should only last roughly a year especially with as light a duty as I've put on these. American Muscle is excellent as always but I'd be leery of this brand.

    Doing it right

    This is a great product that comes with a shack of shims to help you get the angle correct. Do not go off the pictures on AM, most show all the shims being used at a horrible angle when in fact you want it to have as little angle as possible when it's sitting on the ground. My 14 mustang is lowered 1.5 inches and it took the two big shims to do the job and that's it.
