    Features & Details

    • Designed for Optimum Handling
    • Tested in Extreme Conditions
    • Eliminates Body Roll
    • Kit Includes Driver and Passenger Side Ball Joint
    • Fits 2005 to 2010 Mustangs
    Designed For Optimum Handling. Steeda's X5 Ball Joint will greatly improve the suspension geometry on your lowered Mustang by raising the spindle relative to the pivot-point of the ball joint. This raises the roll center back into the correct range, resulting in reduced body roll, quicker steering response and improved overall front tire grip.

    Tested In Extreme Conditions. The X5 ball joints are made in the USA to Steeda's strict specifications by a respected name-brand supplier to Ford, GM, and Chrysler. Except for their unique custom length, these ball joints are constructed from the the same OEM materials that have been extensively tested in Ford police cars and other heavy duty service vehicles, where they have far exceeded the durability of current production "stock" ball joints.

    Eliminates Body Roll. The X5 ball joint was specifically designed to correct the front roll center geometry. The X5 ball joint features a longer shaft, to raise the spindle in relation to the ball joint pivot point.

    Application. This set of two Steeda X5 ball joints are designed to fit the 2005 to 2010 Mustangs including the V6, GT, Bullitt, and Shelby GT500 models.

    Note: Coupon codes cannot be applied to this product.

    Technical Note: The use of 18" wheels are required for clearance, Steeda highly recommends a bump steer kit be used in conjunction with these X5 balljoints.

    Can these be used on a Mustang with 18" wheels and stock suspension?

    • This Steeda X5 Ball Joint Kit (05-10 All) will work fine with your 18" wheels and stock suspension. I recommend pairing this kit up with a Steeda bumpsteer kit Item #16152 (

    Will these fit on 20" rims? It states that 18" rims are reqired for clearance, is that the minimum size? I have 20" rims that i want to install these on. Will they fit even though it states that 18" rims are "required". Im assuming thats just the minimum tire size that it will work on.

    • Correct, the 18" wheels is the minimum requirement in order to have enough clearance for these ball joints. Using the 20" wheels would give you plenty of room.

      Car feels more planted

      Bought these Steeda X5 ball joints to go with the Ford Racing lowering springs, Steeda bump steer kit, rear axle control arm and panhard bar. My 06 GT is way more planted to the pavement and gave me a lot more confidence in hitting the corners on the road course. Definitely recommend them to anyone who lowers their S197 and is looking to make their car handle a lot better.

      They’re worth it

      After lowering it seemed like my body roll and handling got worse. These and the bumpsteer kit got my front end to act right. I put them in new arms then swapped out the whole thing

      Steeda X5 Ball Joint FYI

      Ball joints appear to be equal quality to OEM units. Install time is hard to judge because I completely removed the arms and changed out the front bushings to polyurethane while everything was apart. Time will tell if the raised pickup point helps suspension geometry or not and I still need a proper alignment but drives well so far. Biggest complaint is with the rubber boots. One of them had a metal ring molded into it which presses onto the joint, holds it down tight and keeps dirt out. The other one did not so I had to get "creative" and make it work. I'm sure Steeda doesn't make the rubber boots (or the ball joint) so it's simply bad Q.C. while packing the box. This was my first time pressing ball joints and I was able to do it with a rented tool from a local auto parts store. Had a VERY difficult time getting the ball joint started straight and it took me hours of fiddling around before it finally went in without shifting. The other side only took about 20 minutes of swearing to actually press and it went in totally straight. The impact wrench really helped drive the thing home. Something else which wasn't totally obvious to me was how far to press the ball joint into the control arm. There is no shoulder machined into the ball joint base to which you would press it to. After more swearing, googling, and staring at the single page install instructions, I decided to take it literally and press it only far enough to get the snap ring on. After thinking a while about how the weight sits on it, that is the natural settling point if the ball joint slipped a bit. I doubt they will because those knurlings around the edge seemed to really bite into the stock control arm.

      Need these if you're lowered!

      Need these taller joints if your car is lowered to fix your handling. I've had them before without any issues. Due a shop making a mistake I ended up replacing them with the whiteline ones, which ended being loose in the control arm receptacle. Going back to these now. Quality product and American Muscle of course gives fast service and shipping!

      Required for lowered cars.

      lowering your car without geometry correction is a mistake. I rode around without these for a few thousand miles, so the difference was very apparent afterwards.

      Probably shouldn't purchase by itself.

      The X5 ball joints feel nice and look nice (even though you will never see them) but if you are going to be replacing these you should most definitely replace the tie rod ends as well! If your ball joints are going bad your tie rod ends are probably following suit and after replacing ethier of these parts you will need a alignment. It's simply best to save time and money and replace them together. Also if your not a mechanic with a shop getting these in is quite difficult so leave yourself plenty of time.

      X5 ball joints

      Bought these for my 05 GT to improve handling since I'm lowered 2inches but they brought me more pain then anything. I had them pressed in and one of lips for the snapper ring broke off, the other ball joint just bent my LCA to the point where I had to have a new one. So I ended up ordering the ford racing LCA and not even attempting to put these ball joints in those. Called steeda to try and get new ball joints since one had broke and the other wouldn't fit in correctly, the guy acted like they could help me but in the end nothing was done for me at all. Wish I got to notice the improvement of the stock ball joints.

      Improvement over stock

      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.

      A++ Steeda X5 Ball Joints

      The car feels so much better around curves. Not a lot of body roll any more , which makes going around those turns more fun! A bump steer kit helps this dramatically. Make sure to get an alignment after these are installed. Also, if you have major vibration / shaking in the steering wheel or car in general after the alignment, get the tires balanced. Balancing the tires cleared that vibration I had right up.

      Does exactly what I expected/wanted it to do. The price is rediculous on these those and all others like them. They should cost only slightly more than the stock replacements, not 3 times that much.

      Rock solid steering for lowered cars.

      Great product, much beefier than stock. You will need an alignment after, it does change your toe angle by a few degrees. Also you will want to add a bump steer kit, I still need to and it is manageable, but the roads here a smooth. Ymmv.

      Body roll no more

      If you've lowered your car, these are a must. The body roll is gone and the steering feels a ton better (also installed a FRPP bumpsteer kit).

      After lowering my 07 GT the handling left a little to be desired. But after installing the Steeda X5 ball joints I noticed a huge improvement. If you plan on installing these yourself make sure you have a good ball joint press.

      The control is back in the geometry not the tire!

      As I said in the summary for a lowered car the X5 ball joint must be paired with Steeda bump steer kit. The result is that your bump steer geometry is corrected after being lowered. The steering is nice and tight, responsive, and the tires feel flat when cornering. Best of all in hard cornering say goodbye to tire squeeling when chasing an RX8 around a corner. I'm pleased with this product and happy with the shop's install but it did take them 4 hours to do it as they had to press the ball in the control arm. The quality of these two parts will make you smile when you see the loss of tire squeel and bumps and flukes in the road don't rock your baby off the road or track. IT's a must for lowered applications and will bring a nice smile when you go around a corner and just feel the precision, your confidence goes up, you push it even harder around the corner and you still cant get a tire squeel. I love it!

      Missing parts?

      Ok so I bought this and it took about 4ish days to get to So Cal. It didn't come with ANYTHING in the picture besides the actual ball joints: no blue thing, no bolt/nut, no elbow joint, and no washer thing. It took a LONG time to take out the factory ball joint and a long time to get these into the socket. I guess everything worked out in the end. I would suggest you get them professionally installed, it will save you a lot of time and hassle.
