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.

The extended shaft puts your control arms back to the original geometry. They are so well made. I was very impressed.

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.

    Great Product

    Did exactly what it was supposed to do and the install was easy due to the ball joint kit I had. I had the car aligned and it now feels great and good response in the steering.

    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.

    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.

    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.

    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.

    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).

    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.

    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.
