    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.

        5 Top Rated Questions

        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.

        Hello, I was curious if these will work with factory shocks and struts, or will I have to upgrade?

        • While these will work with factory shocks and struts, we recommend upgrading them when lowering your Mustang.

        Helpful (5)

        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.

        Helpful (4)

        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.

        Hello I have a 2005 Mustang GT with saleen wheels on it. The wheels are 20s 275 on all corners. Will I rub? Thank you!!

        • With the Ford Performance Lowering K-Springs offering a 1.5" drop all around, we unfortunately would not be able to confirm fitment for the 275 series tire on the front. A 275 has proven to be too large on many applications, however, with a proper offset it is plausible.

            Rough ride

            Purchased these springs along with SR performance rear shocks, front struts and Ford performance jounce bumper kit. I'm getting a really bouncy rough ride. Not sure if the SR performance shocks are not good enough or if it is the springs. The car does handle and does not nose dive as much. I did not need a panhard bar. It took me approx. 2 hours to install.

            Great springs

            I knew if they were by Ford Racing they had to be perfect for the car. I was correct. It looks and drives great. I would recommend them.

            Great ride and height

            Great ride height eliminates the wheel gap, the ride quality improves as well with the stiffer springs. Looks great with my 19 inch rims will look better with 20 inch rims in the near future.

            Substandard after a couple of years on board.

            I bought these a couple years or so ago...they started collapsing, thus had to replace. I only daily drive with some spirited runs here and there. I went to some BMR linerar rate springs for now, but still need fronts. Let's just say I can't easily get a jack under the front of my car and now my alignment is off as well as was my pinion angle before, ate my jounce bumpers off the rear, and allowed shock bottoming which busted my D-specs. Have a set of Viking Warriors under the back now, but I put the blame on the springs. SMH... c'mon now FRPP.

            2008 gt c/s

            $340 install. Just had these put in this weekend along with a hotchkis panhard bar, and am beyond happy with both the new stance, and also with the new ride quality. It no longer feels like a sloppy unpredictable ride and now feels like it can handle some twisties. Between these springs, the panhard bar and a bmr strut tower brace it's a completely different car with great road comfort and worth the bit of investment. Did not need the camber plates or alignment, so either these are a fantastic fit, or my mechanic is the man.

            massive improvement in looks

            Waited a year to lower my car. what a stupid decision! these springs lowered the car about to inches and got rid of the ugly lifted stance. The car no long nose dives as hard as it used to under breaking and gives confidence on turns. BUT the biggest benefit is the look! Great buy at this price.

            Ford Springs

            The ride is really good. Stiffens up compared to stock springs and makes it a more comfortable ride. While riding with passengers its very comfortable as it is stiff and there's very little body roll.
