    Review & Install Video

    Improves Handling. Installing a set of progressive rate Ford Racing K-Springs will lower your Mustang's center of gravity, which will reduce squat during acceleration, body roll in the corners, and excessive nose-dive under hard braking. Ford Racing K-Springs are great for daily driving, street, and even occasional track use.

    Aggressive Stance. The Ford Racing K-Springs not only improve the handling of your S197 Mustang, but they also improve the overall appearance by lowering the ride height approximately 1.5" to eliminate that nasty raised 4x4 truck look for a more aggressive muscle car stance.

    Clears Stock and Aftermarket Wheels & Tires. These lowering springs were engineered to be compatible with your stock size wheels and tires, as well as AmericanMuscle's pre-configured wheel and tire combo kits (specific to your generation), to assure proper clearance with no rubbing issues.

    Application. This set of four Ford Racing K-Springs are designed specifically for use on the 2005 to 2010 GT Mustangs Coupes. They will also fit 2011 and newer GT Coupes when used in combination with Ford Racing M-18183-C upper strut mounts and M-18000-A dampers (sold separately). Does not fit V6 or convertible models.

    Will these work together on a 2014 GT with KONI STR.T Shock Strut Kit (11-14 GT, V6) and if they do will the the mounts have to be changed or can factory mounts be used?

    • The Ford Performance Lowering K-Springs and KONI STR.T Shock and Strut Kit will be compatible with one another. No new strut mounts are needed with this setup.

    What is exactly is it that makes these springs not fit on a Convertible? There's no difference between the stock springs on the Coupe or Convertible.

    • These springs will not work on a convertible as the convertible Mustangs have a different weight, weight distribution, and different structural integrity which will change the way specific springs (such as these) will perform on a coupe vs a convertible.

    Do I need to upgrade my struts or will these be fine with the stock struts?

    • We generally recommend the Ford Performance shock/strut kit will these lower springs. They can be found here: https://www.americanmuscle.com/frpp-shockstrut-0514gtv6.html.

    How much will these drop an 11 GT with the Track Pack? Also, will I need to replace the panhard bar or the control arms?

    If I install these springs, will I need to buy an adjustable link arm for the swaybar?

    • The Ford Performance Lowering K-Springs do not require an adjustable link arm for the sway bar. Although it would be a ideal upgrade, it is not necessary for installation of these springs.

    I just installed these springs on my car, they look great! My only question is when I go over bumps I noticed a little bit of a clunk in the rear end. Assuming I installed them correctly, is this something that will go away after the break in period? Or is could that indicated that I need news struts? My car only has 73000 miles. Thanks. 1 answer

      Very satisfied!

      I bought these springs to go with Kono STR.T Orange shocks and struts. They went together perfectly. The ride is extremely better than stock. Yeah the bumps are there, but the dampening of them is much more superior and comfortable than the old bouncy stock setup. If you buy the Koni shocks specific to the 2011 model, you do NOT need the GT500 Strut Mounts with these springs. In fact, the GT500 Strut Mount will NOT work in this setup. On the description of these it says you need them but you don't. I also purchased Eibach Adjustable Camber Bolts, which you will need to adjust the of the front wheels. For $700, you get a very nice setup and a nice 1.5" drop. Give the springs some time to settle and you're all set!

      Lowering springs

      Springs installed rather easily , pretty straight forward. Nice quality and a nice paint job . I would recommend replacing the pan hard bar with an adjustable one . But one thing nobody ever talked about was that the front stabilizer bar end links come in contact with the lower control arms . Hence the nasty clunk when the brakes are applied even ever so lightly . Can I be the only person to notice this ? I think not . My local auto parts store found some end links that are 2 inches shorter than stock . Back in business . I recommend finding shorter links before you start or grabbing some adjustable ones . Oh , by the way , springs ride awesome and don’t regret anything!

      Best bang for your buck and top notch quality.

      I've had these on for 10 months now and I'm more than pleased! Gives your 11-14 GT the perfect stance and ride quality without breaking the bank. I was going to going with Eibach, but pulled the trigger on these. I don't regret it.

      2007 mustang springs

      The install was fairly straightforward. The drop these springs give us perfect and the ride quality is almost unchanged, a part from being a little bouncier. I love the way my car looks now and would recommend these springs to anyone looking for a quality drop at a great price!

      Lowered 2007 mustang GT

      I lowered the stang today with the K springs and coupled with the new performance struts it rides fantastic (on rails). I also upgraded the camber plates to the GT350 plates because the stock ones are known to go bad fairly quick. I did keep the stock shocks on the rear to save a couple bucks. I admit I am a little worried about the K springs may settle a little too low. Guess we will see in about a week. It finally sits the way a sports car should....looks really good.

      Good

      Installed on my convertible even though it said it doesn't fit. New shocks, struts, and bump stumps installed at same time. Ride is obviously worse than stock, but not terrible. I had some Vogtlands on my 2005 GT coupe I owned in the past, and I felt they rode worse although I didn't change the shocks and struts on that one (the 05 only had about 5k miles when installed the Vogtland springs, so they weren't worn out). Looks much better!

      Great springs, love the stance

      At first I wanted to go with the P springs because I was afraid to be too low, but let me tell you that I was wrong. The K springs are the way to go, the stance is super aggressive and I have yet to bottom out even with the horrible roads and my steep driveway. Can't go wrong with FRPP parts.

      Great Springs and handling

      Give me an inch and a half drop all the way around yet still maintained a tad bit of rake in the rear which am happy with. I paired them with koni orange shocks and struts an adjustable panhard bar and overall the car handles amazing compared to stock suspension. Highly recommend since they are much cheaper than other spring options
