    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.

    If I install these lowering springs and put 1.5 inch spacers will I have trouble with rubbing my fenders when turning the wheels?

    • Tire clearance will depend on wheel offset and tire size, typically we do not recommend 1.5" spacers in the front of a lowered car as these will push most wheels out too far and cause rubbing

    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.

    On a 2006 Mustang Get Coupe, is a panhard bar required for installation?

    • While not required with the Ford Performance Lowering K-Springs a panhard bar would be a great addition to help recenter the axle.

      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

      Springs are a great value and ride really well. I used these to replace my Ford Racing P-Springs since I wanted a little lower ride height. Worked perfect! Easy swap out in only a few hours....

      Perfect drop!

      These springs were a perfect drop for me. Nice not to have to use caster camber plates, just Eibach adjustable camber bolts and still be within specs. I did upgrade to Koni shocks and struts, along with new Ford Performance GT 500 strut mounts at the same time. All together, these still make your Mustang a great daily driver. Ride isn't compromised too much. Would recommend changing out the jounce bumper stops too.
